> Subject: [dpdk-dev] [PATCH] net/mlx5: fix VF MAC address set over Bluefield
>
> When trying to set MAC address of an ethethet device and if it was
> a representor, PMD sets the MAC over the corresponding VF instead.
>
> For the case of HPF (Host PF representor on BluueField), PMD shouldn't
> attempt to set it, since it doesn't have any corresponding VF and fails.
>
> This will fix the issue by setting the MAC on the dev directly.
