For drivers supporting TSO or similar features, but that still have PN assignment in software, there's a need to have some memory to store the current PN value. As mac80211 already stores this and it's somewhat complicated to add a per-driver area to the key struct (due to the dynamic sizing thereof) it makes sense to just move the TX PN to the keyconf, i.e. the public part of the key struct. As TKIP is more complicated and we won't able to offload it in this way right now (fast-xmit is skipped for TKIP unless the HW does it all, and our hardware needs MMIC calculation in software) I've not moved that for now - it's possible but requires exposing a lot of the internal TKIP state. As an bonus side effect, we can remove a lot of code by assuming the keyseq struct has a certain layout - with BUILD_BUG_ON to verify it. This might also improve performance, since now TX and RX no longer share a cacheline.
