[PATCH v1 07/12] net/ice/base: allow overriding recipe ID

[Anatoly Burakov <anatoly.burakov@intel.com>]

From: Pandi Kumar Maharajan <pandi.maharajan@intel.com>

With the addition of double VLAN mode on the device, the MAC VLAN filter
add rule was previously matching only the inner VLAN, rather than the
intended outer VLAN. This patch resolves the issue by introducing a new
software recipe ID as part of ice_fltr_info, allowing the base code to
send the newly created recipe ID. This ensures that the filter correctly
matches the outer VLAN when processing packets. Issue is observed in ESXi
environment but this patch introduces a generic solution for all
operating systems by adding a rid_override flag. If the base driver needs
to use a recipe ID different from the shared code default, it can set the
rid variable and enable the rid_override flag. This instructs the shared
code to use the specified rid instead of the default value.
