[dpdk-stable] [PATCH] net/bnxt: fix seg fault on Thor

[Ajit Khaparde]

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")
