Subject: common/cnxk: support multi channel for SDP send queues
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=28b283fa7f7519425c2d26ff9f774c5e5afdf429;p=dpdk.git

common/cnxk: support multi channel for SDP send queues

Currently only base channel number is configured as default
channel for all the SDP send queues. Due to this, packets
sent on different SQ's are landing on the same output queue
on the host. Channel number in the send queue should be
configured according to the number of queues assigned to the
SDP PF or VF device.
