bnx2x: Add support for detection of P2P event packets.
The patch adds support for detecting the P2P (peer-to-peer) event packets.
This is required for timestamping the PTP packets in peer delay mode.
Unmask the below bits (set to 0) for device to detect the p2p packets.
NIG_REG_P0/1_LLH_PTP_PARAM_MASK
NIG_REG_P0/1_TLLH_PTP_PARAM_MASK
bit 1 - IPv4 DA 1 of 224.0.0.107.
bit 3 - IPv6 DA 1 of 0xFF02:0:0:0:0:0:0:6B.
bit 9 - MAC DA 1 of 0x01-80-C2-00-00-0E.
NIG_REG_P0/1_LLH_PTP_RULE_MASK
NIG_REG_P0/1_TLLH_PTP_RULE_MASK
bit 2 - {IPv4 DA 1; UDP DP 0}
bit 6 - MAC Ethertype 0 of 0x88F7.
bit 9 - MAC DA 1 of 0x01-80-C2-00-00-0E.
