Subject: [PATCH] net/bnxt: fix flow director with same cmd different queue
[ upstream commit 3f8a7537f05d96970c6e74aa77b3c7f6a634bf51 ]
When user reissues same flow director cmd with a different queue
update the existing filter to redirect flow to the new desired
queue as destination just like the other filters like 5 tuple and
generic flow.
