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. ==================== Link: https://lore.kernel.org/r/1645555153-4932-1-git-send-email-sbhatta@marvell.comSigned-off-by: Jakub Kicinski <kuba@kernel.org>
