Where does the kernel configuration come from? Is this
a plain defconfig that used to work, or do you have
a board specific config file?

This is most likely caused by the added dependency on
CONFIG_PTP_1588_CLOCK that would lead to the BCMGENET
driver not being built-in if PTP support is in a module.
