[ECOS] PXA255, SMSC 91C111, interrupt only fires twice.

["Joe Porthouse" <jporthouse at toptech dot com>]

All,
	Using the devs_eth_smsc_lan91cxx on a PXA255, I can send and receive
packets with ping under Redboot without a problem (poll mode).
	When including the devs_eth_smsc_lan91cxx driver in my application
code (interrupt mode I assume) I can not receive any packets and the receive
interrupt only fires twice during startup.
	I can see 4 ARP packets being transmitted when the driver starts.
After several seconds I stop the code and can see that my interrupt count is
at two.  I also can examine my edge detected register, interrupt mask, and
interrupt enable and they are all in a start that should be firing another
Ethernet interrupt, but it does not seem to occur.
	Any ideas where to look next?
	I also don't understand why I am logging "[eth_drv_ioctl] Warning:
Driver can't set multi-cast mode".  This did not occur under redboot.
	Any help would be greatly appreciated.
Thanks,

Here's my trace
