    if_mtw - Port from FreeBSD, with bugfixes, and parts re-ported from OpenBSD.
    
    * Reverted some recent changes in FreeBSD for 80211 API changes on their side:
       * reverted ratectl API use in ieee80211_ratectl_tx_update()
       * crypto API change (git 5431dafdb9659fb578f)
       * seqno offload (git cce278510a820785d88)
       * ni->ni_txrate references use (git 7067450010931479f8)
    
    * Re-ported the firmware loading code from OpenBSD. Unfortunately firmware
      loading still is not reliable. Sometimes it appears to be consistentl
      working, and then after a reboot it repeatedly fails with the same code.
    
    * Added some error return-codes back that OpenBSD's code has, but got removed
      in the FreeBSD code. This makes it behave a bit better when it fails.
    
    * Fixed the aggregated RX buffer handling, to split up the mbuf correctly,
      using the m_copym method, based on the corresponding code in if_iwm(4).
    
    * Remove the small pieces of #ifdef IEEE80211_SUPPORT_SUPERG code.
      The driver is not in a shape to worry about extra features like this,
      that may not be in working state anyways.
    
    Tested-with: Allnet ALL-WA0150N
    Taken-from: FreeBSD, OpenBSD
