[PATCH v3 1/3] wifi: mac80211: add ieee80211_tx_peek API

[Jose Ignacio Tornos Martinez]

Hi Johannes

Thank you for the review.
I already had some concerns about the peek approach during development, as
it was difficult to implement cleanly.
Your feedback confirms those doubts, so I am reworking the implementation
to avoid the peek API entirely.
I will send a v4 with the new approach.

Best regards
José Ignacio
