Hi,

So exciting times, for the first pull request for fixes I
have a bunch of security things that have been under embargo
for a while - see more details in the tag below, and at the
patch posting message I linked to.

I organized with Kalle to just have a single set of fixes
for mac80211 and ath10k/ath11k, we don't know about any of
the other vendors (the mac80211 + already released firmware
is sufficient to fix iwlwifi.)

Please pull and let me know if there's any problem.

Thanks,
johannes

  ath11k: Drop multicast fragments (2021-05-11 20:16:30 +0200)

----------------------------------------------------------------
Several security issues in the 802.11 implementations were found by
Mathy Vanhoef (New York University Abu Dhabi), and this contains the
fixes developed for mac80211 and specifically Qualcomm drivers, I'm
sending this together (as agreed with Kalle) to have just a single
set of patches for now. We don't know about other vendors though.
