40GbE Intel Wired LAN Driver Updates 2017-03-29
This series contains updates to i40e and i40evf only.
Preethi changes the default driver mode of operation to descriptor
write-back for VF.
Alex cleans up and addresses several issues in the way that i40e handles
private flags. Modifies the driver to use the length of the packet
instead of the DD status bit to determine if a new descriptor is ready
to be processed. Refactors the driver by pulling the code responsible
for fetching the receive buffer and synchronizing DMA into a single
function. Also pulled the code responsible for handling buffer
recycling and page counting and distributed it through several functions,
so we can commonize the bits that handle either freeing or recycling the
buffers. Cleans up the code in preparation for us adding support for
build_skb(). Changed the way we handle the maximum frame size for the
receive path so it is more consistent with other drivers.
Paul enables XL722 to use the direct read/write method since it does not
support the AQ command to read/write the control register.
Christopher fixes a case where we miss an arq element if a new one is
added before we enable interrupts and exit the loop.
Jake cleans up a pointless goto statement. Also cleaned up a flag that
was not being used.
Carolyn does round 2 for adding a delay to the receive queue to
accommodate the hardware needs.
