Bug 90242 – baselayout 1.12.0_alpha2 cannot set interface MTU

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Chris Fanning 2005-04-24 06:59:09 UTC]

Old /etc/conf.d/net entry used to look like this:
ifconfig_eth2=( "192.168.2.1 netmask 255.255.255.0 broadcast 192.168.2.255 mtu 16110" )

Net entry drops ifconfig and replaces it with config:
config_eth2=( "192.168.2.1 netmask 255.255.255.0 broadcast 192.168.2.255 mtu 16110" )

The MTU setting is ignored.  There is no information in net.example indicating how the MTU can be set.

Reproducible: Always
Steps to Reproduce:
1. config file as mentioned in details.

Actual Results:  
MTU is set to default 1500.

Expected Results:  
MTU should have been set to 16110.

Created attachment 57150 [details, diff]
allows ifconfig style mtu for iproute2

in baselayout-1.12.x, we're trying to move to iproute2 for the default
interface unhandler - and iproute2 sets the MTU value in a diffent way from
ifconfig.

Attached is a patch that allows setting the mtu via the same config.

baselayout-1.12.0-alpha2-r1 fixes this
