Subject: net/bnxt: disable VF representors on Thor
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1438a12cc87ecca49075c3da450409bf629c1a70;p=dpdk.git

net/bnxt: disable VF representors on Thor

In a few cases with Thor device, PMD can segfault when VF
representors are specified. Temporarily fix it by preventing
VF reps for Thor device. This will be addressed in next release.

Fixes: 3fe124d2536c ("net/bnxt: support Thor platform")
