Every rx mpdu cmd is built from cmd_hdr | 80211_hdr. The problem is
that the size of cmd_hdr changes with API changes and we don't know
where the 80211_hdr starts.
By adding the size of cmd_hdr dynamically, we can ensure that we always
know how to parse mpdu frames, without dependending on the API changes.

iwl_trace_data is somewhat confusing. It returns a bool
that tells if the payload of the skb should be added to
the tx_data event. If it returns false, then the payload
of the skb is added to the tx event.
The purpose is to be able to start tracing with
-e iwlwifi
and record non-data packets only which saves bandwidth.
Since EAPOLs are important, seldom and not real data
packet (despite being WiFi data packets), they are
included in tx event and thus iwl_trace_data returns false
on those. This last part was buggy, and because of that,
all the data packets were included in the tx event.
Fix that.

In order to be able to properly record SKBs that didn't come through
mac80211, don't rely on the IEEE80211_TX_CTRL_PORT_CTRL_PROTO flag
but instead check for ETH_P_PAE directly.

ilw@linux.intel.com is not available anymore.
linuxwifi@intel.com should be used instead.
