[dpdk-dev] [PATCH] net/mlx5: fix condition to create default rule

[Dekel Peled]

Previous patch added creation of a default flow rule on port start.
Rule is created under the condition that device is in eswitch mode,
and is not a VF, to make sure rule is created only once.
In Bluefield, where PF representor is used, this condition is not
sufficient. Rule is created twice, causing loss of traffic.

This patch updates this condition, adding check that device is also
not a representor.

Fixes: b67b4ecbde22 ("net/mlx5: skip table zero to improve insertion rate")
