Unable to build tn40xx with support for MV88X3310 in kernel 5.11.0

Hi everyone, according to

https://github.com/acooks/tn40xx-driver/blob/4929c3d06c4082b57938352c7ca615a9f86635d9/Readme#L32

5.11.0 should be supported, however, when I try to build this driver with MV88X3310 support, I can see an error because of implicit declaration of function ‘eth_hw_addr_set’, as you can see:

Not sure if will build without MV88X3310 support. Anyway ... why do you think is this due? Shouldn't I be able to build the driver for kernel 5.11.0?

Thank you very much! 😄
