octeontx2-af: Modify SMQ flush sequence to drop packets
[ Upstream commit 019aba0 ] The current implementation of SMQ flush sequence waits for the packets in the TM pipeline to be transmitted out of the link. This sequence doesn't succeed in HW when there is any issue with link such as lack of link credits, link down or any other traffic that is fully occupying the link bandwidth (QoS). This patch modifies the SMQ flush sequence to drop the packets after TL1 level (SQM) instead of polling for the packets to be sent out of RPM/CGX link.
