The first 5 patches implement the PTP feature on the new BCM5760X chips. The main new hardware feature is the new TX timestamp completion which enables the driver to retrieve the TX timestamp in NAPI without deferring to the PTP worker. The last 5 patches increase the number of TX PTP packets in-flight from 1 to 4 on the older BCM5750X chips. On these older chips, we need to call firmware in the PTP worker to retrieve the timestamp. We use an arry to keep track of the in-flight TX PTP packets. v2: Patch #2: Fix the unwind of txr->is_ts_pkt when bnxt_start_xmit() aborts. Patch #4: Set the SKBTX_IN_PROGRESS flag for timestamp packets.
