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.

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 Andrew
