Subject: sfc: Pass NIC structure into efx_wanted_parallelism()
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=a9a52506277275b73955504bf4df745502a28b8b;p=~shefty%2Frdma-dev.git

sfc: Pass NIC structure into efx_wanted_parallelism()

This lets us identify the NIC affected in case of failure, and
will be necessary to adjust for SR-IOV constraints.
