[1/2] net/bnxt: refactor multi queue Rx configuration
Checks
Commit Message
Eliminate separate codepath/handling for single queue
as the multiqueue code path takes care of it as well.
The only difference being the end_grp_id being 1
now instead of 0 for single queue, but that does not matter
for single queue and does not alter any functionality.
Fixes: 6133f207970c ("net/bnxt: add Rx queue create/destroy")
