[PATCH] ath11k: Fix rx_duration reporting

[Ganesh Sesetti]

Since rx duration is wrongly reported in iw wlanX station dump,
fetch correct rx duration reported in PPDU_END tlv.
Enable PPDU_END, MPDU_START and PPDU_END_STATUS_DONE tlv
reporting in monitor status by default. Pass the sta's Rx duration
to mac80211 in sta_statistics() ops.

Doesn't apply and sha1 is invalid so I can't use 3-way merge. Please
ALWAYS use ath11k-bringup branch as the baseline and don't have any
extra patches applied.

Applying: ath11k: Fix rx_duration reporting
fatal: sha1 information is lacking or useless (drivers/net/wireless/ath/ath11k/core.h).
error: could not build fake ancestor
Patch failed at 0001 ath11k: Fix rx_duration reporting
