Previously, the driver would refuse to load if it couldn't secure
enough VIs from the MC to fulfill its RSS requirements.
This was causing probe to fail on later functions in
configurations where we'd run out of VIs, such as having many
VFs.
This change allows the driver to load with fewer VIs, down to a
minimum of 2. A warning will be printed saying that RSS
requirements were not met, possibly affecting performance.
efx->max_tx_channels needs to be set to avoid going down the
failure path in efx_probe_nic() immediately in the loop after the
probe() NIC-type function.
Also, Set rc=ENOSPC when bombing out of efx_probe_nic due to lack
of VIs.

The multicast hardware counter on 8168/8111 chips is only 32 bit while the

are requested on an irregular basis, an overflow of the hardware counter
can go unnoticed. To count even very large numbers of multicast packets
reliably, add a software counter and remove previously applied code to

By using consistent DMA mapping routines together with a mailbox size of

there are configurations where no phy is configured. Those configurations

To fix the problem, accept error returns from device_get_phy_mode(),

Intel Wired LAN Driver Updates 2015-08-26
This series contains updates to i40e and i40evf only.
Anjali provides a fix for i40e where the part is not receiving multicast
or VLAN tagged packets when in promiscuous mode. This can occur when a
software bridge is created on top of the device. Fixed the legacy and MSI
interrupt mode in the driver, which was non-existent before since we
were assuming MSIX was the only mode that the driver ran in. Fixed the
i40evf driver, where the wrong defines were getting used in the VF
driver.
Mitch fixes a sparse warning about comparing __le16 to u16 so use
le16_to_cpu() to resolve the warning. Also fixed a dyslexic spelling
of invalid.
Shannon adds port.crc_errors to receive CRC error counter, since it
is a receive counter.
Catherine provides a fix to move the stopping of the service task and
flow director to i40e_shutdown() instead of i40e_suspend().
Greg fixes the ethtool offline diagnostic with netqueues, which just need
to be treated the same as virtual functions when someone wants to run the
ethtool offline diagnostic test. Also fixed up code comments for the
i40e ethtool diagnostic test function. Cleans up redundant and unneeded
messages, since the kernel notifies all VXLAN capable registered drivers,
so no need to log this.
Neerav adds the ability to update statistics per VEB per traffic class
and dump it via ethtool.
Jingjing adds support for virtual channel offload to support receive
polling mode in the VF driver.
v2: dropped patch which added helper functions into a header, feedback from
David Miller was to make the functions constant to reduce the driver
footprint, so remove the patch while Anjali works on making the requested
changes.

We work with a single vector in MSI mode too, so apply the same
restrictions as Legacy.
