/* Ideally, we'd support up to MAX_SOCK sockets, but the SA-1100 only
* has support for two. This shows up in lots of hardwired ways, such
* as the fact that MECR only has enough bits to configure two sockets.
* Since it's so entrenched in the hardware, limiting the software
* in this way doesn't seem too terrible.
