====================
bnxt_en: PTP fixes

This series includes 2 fixes for the PTP feature.  Update to the new
firmware interface so that the driver can pass the PTP sequence number
header offset of TX packets to the firmware.  This is needed for all
PTP packet types (v1, v2, with or without VLAN) to work.  The 2nd
fix is to use a different register window to read the PHC to avoid
conflict with an older Broadcom tool.
