This patch adds support for ethernet rxtx mode to the driver. The feature
is enabled via a new module parameter. If enabled to driver will enable
the feature on a per vif basis if all other requirements were met.

Shall we have a generic module parameter instead of a dedicated module
parameter for ethernet mode?
so that we can extend this module parameter for raw mode also like below
/* 0 - Nativi wifi
* 1 - Ethernet mode
*/

Would reserving some bits/separating encapsulation so a mask/shift
could allow for enum/switch? I second Karthikeyan's idea of the
generic module_param--- If you look at the ath10k codebase they have
separate flags for sw/hwcrypto and ethernet and it resulted in needing

Maybe just skip/goto past this if offloading? Totally a style thing,
but if more encapsulation/offloading is added later it might pave the
way for cleaner code?
Totally trivial/not a real issue, but I had the thought that if it
were written in the reverse order, protected && (action || deauth ||
dissassoc), it could shortcut quicker potentially?
