 This is an indication that you built the bcmdhd module with a different
configuration (or maybe even different kernel version) than whatever module (or
core kernel) is providing alloc_etherdev_mqs. When you do a proper kernel build,
it shouldn't happen though. So it looks like you didn't properly install
everything to your target (e.g. you updated the modules but not the kernel).

 It can't find the symbol with the version it requires.
