firewire: core: add tracepoints event for asynchronous inbound phy packet
At the former commit, a pair of tracepoints events is added to trace
asynchronous outbound phy packet. This commit adds a tracepoints event
to trace inbound phy packet. It includes transaction status as well as
the content of phy packet.
This is an example for Remote Reply Packet as a response to Remote Access
Packet sent by lsfirewirephy command in linux-firewire-utils:
async_phy_inbound: \
packet=0xffff955fc02b4e10 generation=1 status=1 timestamp=0x0619 \
first_quadlet=0x001c8208 second_quadlet=0xffe37df7
