function is disabled.
Jumbo frame usually improve the performance
int gigabit.
rx_coalesce=n - Rx frame count each interrupt.
rx_timeout=n - Rx DMA wait time for an interrupt. Proper
values of rx_coalesce and rx_timeout bring
a conspicuous performance in the fast machine.
Ex. rx_coalesce=5 and rx_timeout=750
tx_coalesce=n - Tx transmit count each TxComp interrupt.
Setting value larger than 1 will improve
performance, but this is possible to lower
stability in slow UP machines. By default,
tx_coalesce=1. (dl2k)
tx_flow=[1|0] - Specifies the Tx flow control. If tx_flow=1,
the Tx flow control enable.
rx_flow=[1|0] - Specifies the Rx flow control. If rx_flow=1,
the Rx flow control enable.
This feature need jumbo frame compatible
remote.
rx_coalesce=m - Number of rx frame handled each interrupt.
rx_timeout=n - Rx DMA wait time for an interrupt.
If set rx_coalesce > 0, hardware only assert
an interrupt for m frames. Hardware won't
assert rx interrupt until m frames received or
reach timeout of n * 640 nano seconds.
Set proper rx_coalesce and rx_timeout can
reduce congestion collapse and overload which
has been a bottlenect for high speed network.
For example, rx_coalesce=10 rx_timeout=800.
that is, hardware assert only 1 interrupt
for 10 frames received or timeout of 512 us.
tx_coalesce=n - Number of tx frame handled each interrupt.
Set n > 1 can reduce the interrupts
congestion usually lower performance of
high speed network card. Default is 16.
tx_flow=[1|0] - Specifies the Tx flow control. If tx_flow=0,
the Tx flow control disable else driver
autodetect.
rx_flow=[1|0] - Specifies the Rx flow control. If rx_flow=0,
the Rx flow control enable else driver
autodetect.
