session recoveries induced by some older targets when iSCSI NOP-OUT
and iSCSI CMD pdus are intermixed. Newer iSCSI target systems are
immune to this condition and this parameter is turned ON for quite some
time.
Defaults: 1
Values: Binary parameter, 0/1
The parameters can also be set in the modprobe.conf command. See the
man page for more information.
Checking the
bnx2 Driver
Defaults
The bnx2 driver defaults to the following settings:
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.
Coalesce RX Microseconds: 18 (range is 0–1023)
Coalesce RX Microseconds IRQ: 18 (range is 0–1023)
Coalesce RX Frames: 6 (range is 0–255)
Coalesce RX Frames IRQ: 6 (range is 0–255)
Coalesce TX Microseconds: 80 (range is 0–1023)
Coalesce TX Microseconds IRQ: 80 (range is 0–1023)
Coalesce TX Frames: 20 (range is 0–255)
Coalesce TX Frames IRQ: 20 (range is 0–255)
Coalesce Statistics Microseconds: 999936 (approximately 1 second)
(range is 0–16776960 in increments of 256)
MSI: Enabled (if supported by the 2.6 kernel and the interrupt test passes)
