X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=3e3aa21fe9265bdc45ff795dbcc90bcdd2f1017c;p=deliverable%2Flinux.git

i40e: return the number of enabled queues for ETHTOOL_GRXRINGS

This patch fixes a problem where using ethtool rxnfc command could
let RX flow hash be set on disabled queues. This patch fixes the
problem by returning the number of enabled queues before setting
rxnfc.
