Rajkumar Manoharan 5ce8e7fdcc ath10k: handle ieee80211 header and payload tracing separately 
For packet log, the transmitted frame 802.11 header alone is sufficient.
Recording entire packet is also consuming lot of disk space. To optimize
this, tx and rx data tracepoints are splitted into header and payload
tracepoints.

To record tx ieee80211 headers

     trace-cmd record -e ath10k_tx_hdr

To record complete packets

     trace-cmd record -e ath10k_tx_hdr -e ath10k_tx_payload
