1d3d0666a6 mka: Add enable_encrypt op and call it from CP state machine
This allows MKA to turn encryption on/off down to the driver.

23c3528a84 mka: Add support for removing SAs
So that the core can notify drivers that need to perform some operations
when an SA is deleted.

6f551abdfc mka: Remove "channel" hacks from the stack and the macsec_qca driver
This is specific to the macsec_qca driver. The core implementation
shouldn't care about this, and only deal with the complete secure
channel, and pass this down to the driver.

Drivers that have such limitations should take care of these in their
->create functions and throw an error.

Since the core MKA no longer saves the channel number, the macsec_qca
driver must be able to recover it. Add a map (which is just an array
since it's quite short) to match SCIs to channel numbers, and lookup
functions that will be called in every place where functions would get
the channel from the core code. Getting an available channel should be
part of channel creation, instead of being a preparation step.

a25e4efc9e mka: Add driver op to get macsec capabilities
This also implements the macsec_get_capability for the macsec_qca
driver to maintain the existing behavior.

5f5ca28414 mka: Pass full structures down to macsec drivers' receive SC ops
Clean up the driver interface by passing pointers to struct receive_sc
down the stack to the {create,delete}_recevie_sc() ops, instead of
passing the individual properties of the SC.

Clean up the driver interface by passing pointers to struct transmit_sc

Clean up the driver interface by passing pointers to structs transmit_sa
and receive_sa down the stack to get_receive_lowest_pn(),
get_transmit_next_pn(), and set_transmit_next_pn() ops, instead of
passing the individual arguments.

ec958aee32 mka: Remove cs_len argument from the set_current_cipher_suite functions
This is a known constant value (CS_ID_LEN, i.e., the length of the EUI64
identifier) and does not need to be provided separately in these
function calls.
