Re: Network problem...

Hi Michael
Well the old "default" interface "tlp0" delivered a better  
throughput.. and that's just plain old 10Mb Ethernet, whereas this  
one is 100Mb
and when i try to "ftp" from the NetBSD box to a MacOSX box... the  
thoughput in receiving is pretty much the same....

so.. I _think_ the PCCard do have a problem...(and it does provide  
much higher throughput with MacOSX)

BTW: the switch in between is 100Mb as well....
and another thing... the NetBSD box did grind to a halt last night  
with a ton of the following:

rtk0: unable to allocate Rx mbuf
rtk0: unable to allocate Tx mbuf
