I don't know about that uC/OS-II port, but in general, operating system 
ports don't care for or even use interrupt handlers. Interrupt handlers 
are used by another part of the port: your ethernet MAC driver (as 
Nicolas has written, the MAC driver is not included in the OS port).

The OS port only has to supply functions to globally enable or disable 
all interrupts (for critical regions: sys_arch_protect function etc.).
