I think this can be split pretty nicely into 3 patches:
- add IFLA_MACSEC_OFFLOAD to macsec_rtnl_policy (probably for net
with a Fixes tag on the commit that introduced IFLA_MACSEC_OFFLOAD)
- add offload to macsec_fill_info/macsec_get_size
- add IFLA_MACSEC_OFFLOAD support to changelink
The subject of the last patch should also make it clear that it's only
adding IFLA_MACSEC_OFFLOAD to changelink. As it's written, someone
could assume there's no support at all via rtnl ops and wonder why
this patch isn't doing anything to newlink, and whether/why this
IFLA_MACSEC_OFFLOAD already exists.
