mtu MTU: Maximum Ethernet payload size, in bytes. MTU above 1500 is allowed
only when the speed is 1 Gbps.
Minimum: 1024.
Maximum: 9000.
Default: 1500.
pktsize=bytes Specifies the package size in bytes of each test frame. The default size of the
test frame will be three bytes less than the MTU size currently set. Only valid
for the diagnose operation.
recv_coal_ticks
Max Recv Coalesce Ticks: Maximum time for the NIC to wait after receiving a
frame before it raises an interrupt. This and other interrupt tunables must be
modified with care.
Minimum: 0.
Max: 10000000.
Default: 0.
recv_max_bufs
Max Recv Buffers: Maximum number of receive descriptors for the NIC to
coalesce before it raises an interrupt. This and other interrupt tunables must
be modified with care.
Minimum: 1.
Maximum: 256.
Default: 1.
rx_cko Receive Checksum Offload: Hardware TCP/UDP (IPv4) receive checksum
offload.
Values:Off,On.
Default: Off.
rx_fctrl Receive Flow Control: Ability of the interface to receive Ethernet Flow control
frames.
Values:Off,On.
Default: On. (Case insensitive)
send_coal_ticks Max Send Coalesce Ticks: Maximum time for the NIC to wait after sending a
frame before it raises an interrupt. This and other interrupt tunables must be
modified with care.
Minimum: 0
Maximum: 10000000
Default: 150.
send_max_bufs Max Send Buffers: Maximum number of send descriptors for the NIC to
coalesce before it raises an interrupt. This and other interrupt tunables must
be modified with care.
Minimum: 1
Maximum: 128.
Default: 10.
speed Speed, Duplex and Autonegotiation: Actual values of speed, duplex and
autonegotiation if the link is up; the configured values otherwise.
Note that, for 1000Base-SX, the speed is always fixed at 1 Gbps, and the
duplex is always Full. Only the autonegotiation can be turned on or off. So,
the valid values to set for speed in the command line for 1000Base-SX are
auto_on and auto_off (case insensitive).
For 1000Base-T, it is essential that the link partner have the same speed,
duplex and autonegotiation settings as the NIC being configured.
The speed can be forced to 10 or 100 Mbps, with Full or Half Duplex, with
autonegotiation off. This is done by setting speed to one of
10HD, 10FD,
100HD,or100FD (case insensitive).
However, the 1000Base-T standard (IEEE ) does not allow forcing the speed to
1 Gbps. The user can only enable autonegotiation and connect the NIC to a
