@neethajohn The last two comments are addressed. Please take a look again. Thanks |
@bingwang-ms , to support the additional queues, you will also need to make a change in buffermgr to not hardcode the lossless pgs - https://github.com/Azure/sonic-swss/blob/master/cfgmgr/buffermgr.h#L14 |

Signed-off-by: bingwang bingwang@microsoft.com What I did Currently, the entry pfc_enable in table PORT_QOS_MAP is used to specify pfc and pfc_watchdog are enabled on which queues. To avoid PFC deadlock in Dual-ToR scrnario, we are going to introduce two extra lossless queues to carry bounced back traffic.HLD. The extra lossless queues require another two pfc_watchdogs, and the new watchdogs will be implemented by hardware due to limited resources. The hardware pfc watchdog is not covered in this PR. To specify on which queue to enable pfc watchdog, we need to define new table pfcwd_sw_enable. Table Description pfc_enable Specify on which queues to enable PFC pfcwd_sw_enable Specify on which queues to enable software PFC watchdog This PR is to update orchagent to support new field pfcwd_sw_enable . As two extra lossless PGs (2 and 6) are to be added, buffermgrd is also updated in this PR to generate lossless profile for the new PGs.
