Hi SCSI mailing list,
I'd like to propose following additions to sysfs to export statistics
of FCoE host bus adapters.
The additions can be broadly divided into capabilities of FCoE HBA
adapter and its statistics.
I am thinking of extending HBA specific informations inside the
fc_host(/sys/class/fc_host/hostX) and make a seperate
attribute_group(/sys/class/fc_host/hostx/fcoe_statistics/) for fcoe
statistics.
FCoE HBA specific information
1) enode_mac_address /* Factory programmed MAC address */
2) vn_port_mac_address; /* Current programmed MAC address */
3) fcf_mac_address; /* FCF mac address */
4) vlan_id: /* Local VLAN ID */
5) mac_addressing_model /* Whether SPMA or FPMA */
Current DCBX parameter details:
PGID (Priority group ID)
1) pgid_priority_group_0; /* Priority group ID of priority group
0 */
2) pgid_priority_group_1; /* Priority group ID of priority group
1 */
3) pgid_priority_group_2; /* Priority group ID of priority group
2 */
4) pgid_priority_group_3; /* Priority group ID of priority group
3 */
5) pgid_priority_group_4; /* Priority group ID of priority group
4 */
6) pgid_priority_group_5; /* Priority group ID of priority group
5 */
7) pgid_priority_group_6; /* Priority group ID of priority group
6 */
8) pgid_priority_group_7; /* Priority group ID of priority group
7 */
Bandwidth assignment per priority group
1) priority_group_0_bw_percentage; /* Priority group 0 bandwidth
percentage */
2) priority_group_1_bw_percentage; /* Priority group 1 bandwidth
percentage */
3) priority_group_2_bw_percentage; /* Priority group 2 bandwidth
percentage */
4) priority_group_3_bw_percentage; /* Priority group 3 bandwidth
percentage */
5) priority_group_4_bw_percentage; /* Priority group 4 bandwidth
percentage */
6) priority_group_5_bw_percentage; /* Priority group 5 bandwidth
percentage */
7) priority_group_6_bw_percentage; /* Priority group 6 bandwidth
percentage */
8) priority_group_7_bw_percentage; /* Priority group 7 bandwidth
percentage */
Priority based flow control (PFC)
1) pfc_enabled_priority_0 /* Flow control is enabled in both
direction for priority 0 */
2) pfc_enabled_priority_2 /* Flow control is enabled in both
direction for priority 1 */
3) pfc_enabled_priority_3 /* Flow control is enabled in both
direction for priority 2 */
4) pfc_enabled_priority_4 /* Flow control is enabled in both
direction for priority 3 */
5) pfc_enabled_priority_5 /* Flow control is enabled in both
direction for priority 4 */
6) pfc_enabled_priority_6 /* Flow control is enabled in both
direction for priority 5 */
7) pfc_enabled_priority_7 /* Flow control is enabled in both
direction for priority 6 */
8) pfc_enabled_priority_8 /* Flow control is enabled in both
direction for priority 7 */
Statistics:
1) fcoe_tx_frames; /* number of FCoE transmit frames */
2) fcoe_tx_words; /* number of tx words */
3) fcoe_rx_frames; /* number of FCoE receive frames */
4) fcoe_rx_words; /* number of rx words */
5) fcoe_rx_drop_frames; /* number of FCoE dropped
receive frames */
6) fcoe_tx_pause_pkts; /* number of FCoE transmit
PAUSE packets */
7) fcoe_rx_pause_pkts; /* number of FCoE receive
PAUSE packets */
8) fcoe_tx_cbfc_pause_frames_0; /* number of class based flow
control transmit PAUSE frames on PG 0 */
9) fcoe_tx_cbfc_pause_frames_1; /* number of class based flow
