Subject: net/ice: fix flow director rule after device stop
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c8a9eacb210f21be592c7e7b6c37afdd32d40dfc;p=dpdk.git

net/ice: fix flow director rule after device stop

By moving irq enable/disable from device start/stop to FDIR
setup/teardown, FDIR queue irq config is independent of LAN queue irq
config. So device stop will not cause FDIR rule failure.

Fixes: 84dc7a95a2d3 ("net/ice: enable flow director engine")
