a7f4b98896 bna: fix list corruption
Use list_move_tail() to move MAC address entry from list of pending
to list of active entries. Simple list_add_tail() leaves the entry
also in the first list, this leads to list corruption.

6c3f5aef11 bna: fix Rx data corruption with VLAN stripping enabled and MTU > 4096
The multi-buffer Rx mode implemented in the past introduced
a regression that causes a data corruption for received VLAN
traffic when VLAN tag stripping is enabled. This mode is supported
only be newer chipsets (1860) and is enabled when MTU > 4096.

When this mode is enabled Rx queue contains buffers with fixed size
2048 bytes. Any incoming packet larger than 2048 is divided into
multiple buffers that are attached as skb frags in polling routine.

The driver assumes that all buffers associated with a packet except
the last one is fully used (e.g. packet with size 5000 are divided
into 3 buffers 2048 + 2048 + 904 bytes) and ignores true size reported
in completions. This assumption is usually true but not when VLAN
packet is received and VLAN tag stripping is enabled. In this case
the first buffer is 2044 bytes long but as the driver always assumes
2048 bytes then 4 extra random bytes are included between the first
and the second frag. Additionally the driver sets checksum as correct
so the packet is properly processed by the core.

The driver needs to check the size of used space in each Rx buffer
reported by FW and not blindly use the fixed value.

4c52b1da53 bna: fix error handling
Several functions can return negative value in case of error,
so their return type should be fixed as well as type of variables
to which this value is assigned.

The problem has been detected using proposed semantic patch

ade4dc3e61 bna: fix interrupts storm caused by erroneous packets
The commit "e29aa33 bna: Enable Multi Buffer RX" moved packets counter
increment from the beginning of the NAPI processing loop after the check
for erroneous packets so they are never accounted. This counter is used
to inform firmware about number of processed completions (packets).
As these packets are never acked the firmware fires IRQs for them again
and again.

138b15ed87 drivers/net: remove all references to obsolete Ethernet-HOWTO
This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it.  And there is
no value in anyone else taking over updating it either.

However the references to it continue to spread as boiler plate text
from one Kconfig file into the next.  We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.

No code is changed in this commit, just Kconfig help text.

Bug in the driver initialization causes soft-lockup if firmware

The problem is that bfa_nw_iocpf_timeout() calls again
bfa_ioc_poll_fwinit()... etc. The bfa_ioc_poll_fwinit() should directly
send timeout event for iocpf and the same should be done if firmware
download into HW fails.

6654cf60ab bna: allow transmit tagged frames
When Tx VLAN offloading is disabled frames with size ~ MTU are not
transmitted as the driver does not account 4 bytes of VLAN header added
by stack. It should use VLAN_ETH_HLEN instead of ETH_HLEN.

The second problem is with newer BNA chips (BNA 1860). These chips filter
out any VLAN tagged frames in Tx path. This is a problem when Tx VLAN
offloading is disabled and frames are tagged by stack. Older chips like
1010/1020 are not affected as they probably don't do such filtering.

1c53730a04 bna: Support TSO and partial checksum with non-accelerated vlans.
This device claims TSO and checksum support for vlans.  It also
allows a user to control vlan acceleration offloading.  As such,
it is possible to turn off vlan acceleration and configure a vlan
which will continue to support TSO.

In such situation the packet passed down the the device will contain
a vlan header and skb->protocol will be set to ETH_P_8021Q.
The device assumes that skb->protocol contains network protocol
value and uses that value to set up TSO information.  This results
in corrupted frames sent on the wire.

This patch extract the protocol value correctly and corrects TSO
and checksums for non-accelerated traffic.

c36c9d50cc bna: fix performance regression
The recent commit "e29aa33 bna: Enable Multi Buffer RX" is causing
a performance regression. It does not properly update 'cmpl' pointer
at the end of the loop in NAPI handler bnad_cq_process(). The result is
only one packet / per NAPI-schedule is processed.

dabf24d168 bna: fill the magic in bnad_get_eeprom() instead of validating
A driver should fill magic field of ethtool_eeprom struct in .get_eeprom
and validate it in .set_eeprom. The bna incorrectly validates it in both
and this makes its .get_eeprom interface unusable.
