Hello,
In lib.core the MTU value that is queried from the ip utility
finds itself added a value of 100:
get_device_mtu1() # $1 = device
{
local output
output="$($IP link list dev $1 2> /dev/null)" # quotes required for /bin/ash
local mtu
if [ -n "$output" ]; then
mtu=$(find_mtu $output)
if [ -n "$mtu" ]; then
[ $mtu = 1500 ] || echo mtu $(($mtu + 100))
fi
fi
}
What would be the reason as to why a value of 100 was chosen.
Many thanks.------------------------------------------------------------------------------
