[dpdk-dev] [PATCH] net/bnxt: disable vector mode if flow mark is used

[Stephen Hemminger <stephen@networkplumber.org>]

Since vector mode can't be used with flow mark actions.
The choice of vector or non-vector mode is done dynamically
earlier in the initialization process (config) and the user
application has no direct control over the selection.

Therefore the best resolution to the conflict is for
the driver to disable vector mode if it needs to.
