The transmit queue length (also known as the "txqueuelen" parameter) is a setting that controls the size of the transmit queue for a network interface. The transmit queue is a buffer that holds packets that are waiting to be transmitted over the network.
To increase the transmit queue length on a Linux system, you can use the ifconfig command.
Here is the general syntax for increasing the transmit queue length with ifconfig:
ifconfig interface txqueuelen value
Replace "interface" with the name of the network interface, and "value" with the desired transmit queue length.
For example, to increase the transmit queue length for the eth0 interface to 1000, you can use the following command:
ifconfig eth0 txqueuelen 1000
Note that the transmit queue length is specified in bytes, not packets.
