[net,2/3] octeontx2-pf: Fix PFC TX scheduler free
Commit Message
During PFC TX schedulers free, flag TXSCHQ_FREE_ALL was being set
which caused free up all schedulers other than the PFC schedulers.
This patch fixes that to free only the PFC Tx schedulers.
Fixes: 99c969a83d82 ("octeontx2-pf: Add egress PFC support")
