TABLE 4-11 Read-Only Link Partner Capabilities (Continued)
Parameter | Description | |
|
|
|
lp_cap_10hdx | 0 | = No 10 Mbit/sec |
| 1 | = 10 Mbit/sec |
lp_cap_asm_pause | 0 | = Not asymmetric pause capable |
| 1 | = Asymmetric pause towards link partner capability |
lp_cap_pause | 0 | = Not symmetric pause capable |
| 1 | = Symmetric pause capable |
|
|
|
If the link partner is not capable of autonegotiation (when lp_autoneg_cap is 0),
the remaining information described in is not relevant and the parameter value = 0.
If the link partner is capable of autonegotiation (when lp_autoneg_cap is 1), then the speed and mode information is displayed when you use autonegotiation and the link partner capabilities.

TABLE 4-12 Transmit and Receive Parameters
Parameter | Description |
|
|
| Number of Physical layer |
xcvr_inits | link parameters using NDD this increments. |
rev_id | Revision ID of the GigaSwift Ethernet device useful for recognition |
| of device being used in the field. |
xcvr_addr | GMII/MII Physical layer device address for management interface. |
xcvr_id | GMII/MII Physical layer device Identification Decimal copy of MII |
| registers 2 and 3. |
lb_mode | Copy of the Loopback mode the device is in, if any. |
qos_mode | When zero, the TX queues operate in a simple round robin |
| queueing scheme, based on TCP/UDP destination port number. If |
| set the TX queues operate in a scheme designed to provide VLAN |
| priorities. |
tx_starts | Number of times that the driver attempted to transmit a packet. |
tx_dma_bind_fail Number of times a page table entry was not available to allow the driver to map the kernel memory to device accessible memory for
| transmission. |
tx_queue0 | Number of packets queued for transmission on the first hardware |
| transmit queue. |
