Commit 91572088e3fd ("net: use core MTU range checking in core net
|
||
|
|
infra") changed the openvswitch internal device to use the core net
|
||
|
|
infra for controlling the MTU range, but failed to actually set the
|
||
|
|
max_mtu as described in the commit message, which now defaults to
|
||
|
|
ETH_DATA_LEN.
|
||
|
|
|
||
|
|
This patch fixes this by setting max_mtu to ETH_MAX_MTU after
|
||
|
|
ether_setup() call.
