Data centric bridging designed to eliminate packet loss due to queue overflow by adding enhancements to ethernet network such as proprity flow control etc. This patch adds support for management of Priority flow control(PFC) on Octeontx2 and CN10K interfaces. To enable PFC for all priorities dcb pfc set dev eth0 prio-pfc all:on/off To enable PFC on selected priorites dcb pfc set dev eth0 prio-pfc 0:on/off 1:on/off ..7:on/off With the ntuple commands user can map Priority to receive queues. On queue overflow NIX will assert backpressure such that PFC pause frames are genarated with mapped priority. To map priority 7 to Queue 1 ethtool -U eth0 flow-type ether dst xx:xx:xx:xx:xx:xx vlan 0xe00a m 0x1fff queue 1 Signed-off-by: Hariprasad Kelam <hkelam@marvell.com> Signed-off-by: Sunil Kovvuri Goutham <sgoutham@marvell.com> Signed-off-by: David S.
