txqueuelen in /etc/conf.d/net?

[dufeu]

I'm finally re-visiting my 10G nic configurations in my server and workstation.

Each PC has a Mellanox 10G card connected to SPF+ ports on a switch in the same rack.

I currently have the following configuration to support my usage and faster speed:

• Custom sysctl.conf settings

  /etc/sysctl.conf:

  #       net.core.rmem_max = 212992  # as initialized by kernel #       net.core.wmem_max = 212992  # as initialized by kernel #       -->     for 10G nics - use 16MB, 32MB for long end to end 10G paths #               in addition, use ifconfig (or similar) to increase txqueulen for 10G nics. #               set this in equivalent to /etc/rclocal #                       ifconfig $NIC txqeuelen 10000 #                       ip link set $NIC txqueuelen 10000 net.core.rmem_max = 16777216 net.core.wmem_max = 16777216

  
  
• Custom /etc/conf.d/net configuration. Note that I support up to 3 VMs as normal members of my local LAN.

  /etc/conf.d/net:

  #       single physical nic bridged configuration - intended #       for vm hosts - in this configuration, we want to support #       transparent access between vm clients and other devices #       on the LAN - assumes vm clients are similarly trusted #               eth0 =  motherboard buil-in 1G nic - leave down #               eth1 =  melonix 10G add-on nic - in use # #               set all physical nics to be not needed/required #               for network connected services - we'll be using #               'br0' instead # rc_net_lo_provide="!net" rc_net_eth0_provide="!net" rc_net_eth1_provide="!net" config_eth0=null config_eth1=null # #       tun/tap - like eth# above - null defined to avoid DHCP #               tap# =  need 1 for each concurrent guest session #                       remaining lines assume single vm session #       each 'tap#' represents 1 vm session - tap# assignment is done #       through QEMU invocation using '-net' or '-netdev' # #       your installation may mot have /dev/net installed or, it #       may not have the special mode /dev/net/tun file - it only #       needs to be created 1 time (from 'root' or sudo): #               mkdir /dev/net ; mknod /dev/net/tun c 10 200 # tuntap_tap0="tap" tuntap_tap1="tap" tuntap_tap2="tap" config_tap0=null config_tap1=null config_tap2=null # #               set bridge address - 'eth1' will service the bridge # rc_net_br0_need="net.eth1 net.tap0 net.tap1 net.tap2"" config_br0="192.168.1.200/24" routes_br0="default via 192.168.1.1"

  
  

Can I add 'txqueuelen' to /etc/conf./net? If so, do I add it just to 'br0' or to both 'br0' and 'eth1'?

If I can't add txqueuelen to /etc/conf.d/net, should I add 'ip link set br0 txqueuelen 10000' to /etc/rc.conf? Again, if I add the command for 'br0' to /etc/rc.conf, do I also need to add a command for 'eth1'?

You would set it in /etc/conf.d/net using
