The flag ENTRY_TXD_OFDM_RATE isn't flexible enough
to indicate which rate modulation should be used for
a frame. This will become a problem when 11n support
is added.
Remove the flag and replace it with an enum value which
can better indicate the exact rate modulation.

Restrict drivers to only access link_qual structure during
link tuning. The contents of these fields are for the drivers
and all fields are allowed to be changed to values the driver
considers correct.
This means that some fields need to be moved outside of this
structure to restrict access only to rt2x00link itself.
This allows some code to be moved outside of the rt2x00.h header
and into rt2x00link.c.

The link_tuner() function will always call bbp_read()
at the start of the function. Because this is an
indirect register access has some costs attached
to it (especially for USB hardware).
We already store the value read from the register
into the vgc_level value inside the link structure.
Instead of reading from the register we can read that
field directly and base the tuner on that value.
This reduces the time the registers are locked with
the csr_mutex and speeds up the link_tuner processing.

gfar_vlan_rx_register() checks for "if (old_grp == grp)" and tries

According to net/8021q/vlan.c VLAN core issues rx_register() callback:

A link change interrupt might be queued and activated after the loopback was set
and it will cause the loopback to fail. The PHY lock should be kept until the
loopback test is over.
That implies that the bnx2x_test_link should used within the loopback function
and not bnx2x_wait_for_link since that function also takes the PHY link

The tun code does not cope gracefully if the network device goes away before
the tun file descriptor is closed. It looks like we can trigger this with
rmmod, and moving tun devices between network namespaces will allow this
to be triggered when network namespaces exit.
To fix this I introduce an intermediate data structure tun_file which
holds a count of users and a pointer to the struct tun_struct. tun_get
increments that reference count if it is greater than 0. tun_put decrements
that reference count and detaches from the network device if the count is 0.
While we have a file attached to the network device I hold a reference
to the network device keeping it from going away completely.
When a network device is unregistered I decrement the count of the
attached tun_file and if that was the last user I detach the tun_file,
and all processes on read_wait are woken up to ensure they do not
sleep indefinitely. As some of those sleeps happen with the count on
the tun device elevated waking up the read waiters ensures that
tun_file will be detached in a timely manner.

Currently the tun code suffers from only having a single word of

This results in peculiar holding of references to the network namespace
as well as races between free_netdevice and tun_chr_close.

This patch makes igb invoke the GRO hooks instead of LRO. As
GRO has a compatible external interface to LRO this is a very
straightforward replacement.
Three things of note:
1) I've kept the LRO Kconfig option until we decide to enable
GRO across the board at which point it can also be killed.
2) The poll_controller stuff is broken in igb as it tries to do
the same work as the normal poll routine. Since poll_controller
can be called in the middle of a poll, this can't be good.
I noticed this because poll_controller can invoke the GRO hooks
without flushing held GRO packets.
However, this should be harmless (assuming the poll_controller
bug above doesn't kill you first :) since the next ->poll will
clear the backlog. The only time when we'll have a problem is
if we're already executing the GRO code on the same ring, but
that's no worse than what happens now.
3) I kept the ip_summed check before calling GRO so that we're
on par with previous behaviour.

Everything should appear identical to the user except that the

I have eliminated efx_rx_mk_skb as the GRO layer can take care

being freed using kfree(). He provided a fix where it was replaced to
kfree_skb(), as it should be.
However, in i2400mu_rx(), the error path was missing returning an
indication of the failure. Changed to reset rx_skb to NULL and return
it to the caller, i2400mu_rxd(). It will be treated as a transient
error and just ignore the packet.
Depending on the buffering conditions inside the device, the data
packet might be dropped or the device will signal the host again for
data-ready-to-read and the host will retry.

Contrary to what the docs say, the 'extended interrupt cause' bit in
the interrupt cause register (bit 1) appears to not be maskable on at
least some of the mv643xx_eth platforms, making writing zeroes to the
interrupt mask register but not the extended interrupt mask register
insufficient to stop interrupts from occuring. Therefore, also write
zeroes to the extended interrupt mask register when shutting down the
port.
This fixes the interrupt storm seen on the Pegasos board when shutting
down the interface.

Commit 66e63ffbc0 ("mv643xx_eth:
implement ->set_rx_mode()") cleaned up mv643xx_eth's multicast filter
programming, but broke it as well.
The non-special multicast filter table (for multicast addresses that
are not of the form 01:00:5e:00:00:xx) consists of 256 hash table
buckets organised as 64 32-bit words, where the 'accept' bits are
in the LSB of each byte, so in bits 24 16 8 0 of each 32-bit word.
The old code got this right, but the referenced commit broke this by
using bits 3 2 1 0 instead. This commit fixes this up.

This reverts commit cd4ccf76bf.
On the Pegasos board, we can't do DMA burst that are longer than
one cache line. For now, go back to using 32 byte DMA bursts for
all mv643xx_eth platforms -- we can switch the ARM-based platforms
back to doing long 128 byte bursts in the next development cycle.

This patch modifies how the tg3 driver handles device firmware.
The patch starts by consolidating David Woodhouse's earlier patch under
the same name. Specifically, the patch moves the request_firmware call
into a separate tg3_request_firmware() function and calls that function
from tg3_open() rather than tg3_init_one().
The patch then goes on to limit the number of devices that will make
request_firmware calls. The original firmware patch unnecessarily
requested TSO firmware for devices that did not need it. This patch
reduces the set of devices making TSO firmware patches to approximately
the following device set : 5703, 5704, and 5705.
Finally, the patch reduces the effects of a request_firmware() failure.
For those devices that are requesting TSO firmware, the driver will turn
off the TSO capability. If TSO firmware becomes available at a later
time, the device can be closed and then opened again to reacquire the
TSO capability.

netif_carrier_off() is sufficient to stop Tx into the driver. Stopping the Tx
queues is redundant and unnecessary. By the same token, netif_carrier_on()
will be sufficient to re-enable Tx, so waking the queues is unnecessary.

Register VLAN ID 0 so that frames with VLAN ID 0 are received and get
their tag stripped when ixgbe is not in DCB mode. VLAN ID 0 means
that the frame is 'priority tagged' only - it is not a VLAN, but the
priority value is the tag in valid. The functions
ixgbe_vlan_rx_register() and ixgbe_vlan_rx_kill_vid() were moved up a
couple functions to correct compiling issues with this change.

to drop DCA hints. This patch forces RO not to be set for

while DCA is enabled and no performance difference was

This is copy and paste from the original driver. As skb_reserve() is
also called within korina_alloc_ring() when initially allocating the
receive descriptors, the same should be done when allocating new space
after passing an skb to upper layers.
