[Bug 1423631] Re: tap interface drops many packets on highload systems

[sean redmond]

I was able to resolve this with the below udev rule:

# cat /etc/udev/rules.d/60-tap.rules
KERNEL=="tap*", RUN+="/sbin/ip link set %k txqueuelen 10000"
#

I used the below to reload udev

udevadm control --reload-rules

I then used the below to apply the rules to already created interfaces:

udevadm trigger --attr-match=subsystem=net
