7.12.3 Trace
The device driver sets up three trace hook IDs (defined in
/usr/include/sys/cdli_entuser.phxent.h). The first hook traces the transmit path,
the second trace the receive path, and the third will trace everything else.
The device driver has three trace points: transmit, receive, and other, and has a
trace table of at least 1000 entries when complied normally. It traces entry/exit
from transmit/receive routines at the interrupt and user layers, as well as on entry
to the interrupt handler when compiled normally.
Table 39 lists these hook IDs.

7.12.4 Error Logging
The device driver logs errors in the error log whenever one of the following errors
occur: hardware failures, DMA operations, and memory faults.
Following are the error log entries returned by the 10/100 Mbps PCI Ethernet
device driver:
ERRID_PHXENT_ADAP_ERR
Indicates that the adapter is not responding to initialization commands.
User-intervention is necessary to fix the problem.
ERRID_PHXENT_ERR_RCVRY
Indicates that the adapter hit a temporary error requiring that it enter network
recovery mode. It has reset the adapter in an attempt to fix the problem.
ERRID_PHXENT_TX_ERR
Indicates that the device driver has detected a transmission error.
User-intervention is not required unless the problem persists.
ERRID_PHXENT_PIO
Indicates the device driver has detected a program I/O error. The driver was
unable to fix the problem. User-intervention is required.
ERRID_PHXENT_DOWN
Indicates that the device has been shutdown due to an irrecoverable error. The
device is no longer functional due to the error. The irrecoverable error that
