net/bnxt: fix ring group on Rx restart
Browse files Browse the repository at this point in the history
[ upstream commit 1b27f82 ]

When an Rx queue is stopped and restarted, as part of that workflow,
for cards that have ring groups, we free and reallocate the ring group.
This new ring group is not communicated to the VNIC though via
HWRM_VNIC_CFG cmd.
Fix to issue HWRM_VNIC_CFG cmd on all adapters now in this scenario.

Fixes: ed0ae35 ("net/bnxt: update ring group after ring stop start")
