Merge branch 'add-ethtool-support-for-completion-queue-event-size'
Subbaraya Sundeep says:
====================
Add ethtool support for completion queue event size
After a packet is sent or received by NIC then NIC posts
a completion queue event which consists of transmission status
(like send success or error) and received status(like
pointers to packet fragments). These completion events may
also use a ring similar to rx and tx rings. This patchset
introduces cqe-size ethtool parameter to modify the size
of the completion queue event if NIC hardware has that capability.
A bigger completion queue event can have more receive buffer pointers
inturn NIC can transfer a bigger frame from wire as long as
hardware(MAC) receive frame size limit is not exceeded.
Patch 1 adds support setting/getting cqe-size via
ethtool -G and ethtool -g.
Patch 2 includes octeontx2 driver changes to use
completion queue event size set from ethtool -G.
