This patch series enables remote KCOV coverage collection for the
mac80211 code that processes incoming 802.11 frames. These changes
make it possible to perform coverage-guided fuzzing in search of
remotely triggerable bugs.


The series consists of two commits.
1. Remember kcov_handle for each sk_buff. This can later be used to
enable remote coverage for other network subsystems.
2. Annotate the code that processes incoming 802.11 frames.
