Linux Driver Software: Broadcom NetXtreme II Network Adapter User Guide "Configure RQ size", used to choose the size of asynchronous buffer queue size per offloaded connections. RQ size is not required greater than 16 as it is used to place iSCSI ASYNC/NOP/REJECT messages and SCSI sense data. Defaults: 16 Range: 16 to 32 Note that Broadcom validation is limited to a power of 2; for example, 16, 32. event_coal_div "Event Coalescing Divide Factor", performance tuning parameter used to moderate the rate of interrupt generation by the iscsi firmware. Defaults: 1 Valid values: 1, 2, 4, 8 last_active_tcp_port "Last active TCP port used", status parameter used to indicate the last TCP port number used in the iSCSI offload connection. Defaults: N/A Valid values: N/A Note: This is a read-only parameter. ooo_enable "Enable TCP out-of-order feature", enables/disables TCP out-of-order rx handling feature on offloaded iSCSI connections. Defaults: TCP out-of-order feature is ENABLED. For example: insmod bnx2i.ko ooo_enable=1 or modprobe bnx2i ooo_enable=1 Driver Defaults bnx2 Driver bnx2x Driver bnx2 Driver Speed: Autonegotiation with all speeds advertised Flow Control: Autonegotiation with RX and TX advertised MTU: 1500 (range is 46-9000) RX Ring Size: 255 (range is 0-4080) RX Jumbo Ring Size: 0 (range 0-16320) adjusted by the driver based on MTU and RX Ring Size TX Ring Size: 255 (range is (MAX_SKB_FRAGS+1)-255). MAX_SKB_FRAGS varies on different kernels and different architectures. On a 2.6 kernel for x86, MAX_SKB_FRAGS is 18.
