The i82557 and i82558 (Speedo3 and Mt. Bachelor) chips take a long time to
digest longer multicast filter lists.
This can be avoided by switching to rx-all-multicast mode sooner.
The parameter that sets this is:
/* Maximum number of multicast addresses to filter (vs. rx-all-multicast) */
static int multicast_filter_limit = 64;
Append the following /etc/conf.modules:
options eepro100 multicast_filter_limit=2;
Please report the result.
If it works, try increasing it -- I'm interested in knowing at what value it
becomes a problem. (I don't have an Appletalk environment to test in...)
