Hi Andrew,
                           Currently net/dsa/slave.c does not have
ndo_change_mtu function.  But shortly I will be submitting a separate
patch outside this fix that has ndo_change_mtu function support added to
DSA switch.  As part of testing the newly added ndo_change_mtu function
for DSA switch it uncovered that new mtu size is not being updated to
netdevice structure. This patch fixes this issue and updates  new mtu size
to  netdevice structure.

Hope this clarifies, let me know if you need any further information.

Regards
Murali

Hi Murali

Please could you give more details. net/dsa/slave.c does not have a
ndo_change_mtu function, so i don't know what you mean by the
reference to DSA.

	  Thanks
