 the simple fix would be to change the  on the marked
 line to =.  but i think the while loop could be tossed
 since malloc panics on failure and since qopen only allocates
 sizeof(Queue) regardless of the limit argument.  i had
 this code when i wrote the myricom driver (qio sets q-limit itself).

 j = ether-mbps;
 if(j  1000)
 j *= 10;
 for(i = 0; j = 100; i++)
 j /= 10;
 i = (128i) * 1024;
 netifinit(ether, name, Ntypes, i);
 if(ether-oq == nil)
 ether-oq = qopen(i, Qmsg, 0, 0);
 if(ether-oq == nil)
 panic(etherreset %s, name);

 by the way, a quick scan shows
 ether2114x
 etherrhine
 are capable of setting mbps to 0 on startup.  this should
 be legal, since ethernet can be connected after boot.

It work's

Thank you.

[9fans] Latest pull killed my server

[vmhaas]

All -
I have been running an all-in-one server on a VMware server virtual 
machine on my Windows laptop.
After executing a 'pull' this morning, the server crashed and I have not 
been able to revive it. Fortunately it was a playground so little of 
value is missing, but I thougt I should ask . . .


I pulled down a copy of today's ISO and had the same results. It seems 
to be panicking when hitting the (virtualized) Ethernet port.


Anyone else seeing this?

TIA

i am not seeing this, but sources venti is down and explains why
pull stepped on important stuff.  replica needs to be more defensive.

regardless, that doesn't explain why the iso worked enough to
get you to a panic.  what is the panic message?
