Hi Bill,

I'm having quite a few problems with my linksys cards.
I think most are caused because I'm connected to a switch
rather than a simple hub.
The cards are the new Version 2 cards (with Wake On Lan)
and use the MX driver.

1) On 3.3-stable, the linksys mx driver detects my network
   connection to a 3COM switch as 100BaseT4.
   However, the kernel then panics because if_media cannot
   support media type 0x28.

   My workarond was to hack the kernel source for if_mx.c
   and stop it detecting 100BaseT4. It now detects 100Base Full
   duplex and works ok.

2) On 4.x-current, the linksys mx driver is connected to
   a Kingston 10/100 Switch.
   It does not detect a carrier on the network.

   If I do ifconfig mx0 media auto I see the 'link in use'
   and '100 Megs in use' LED on my switch
   go on for 2 seconds, then go off for 2 seconds, then go
   on for 2 seconds, then go off for 2 seconds.
   When the link is up, I can ping and use the network etc.
   When the link is down, I have no network connection.

   If I type in ifconfig mx0 media 100basetx
   it all works OK.

Do you have any ideas on these.

I'm willing to test patches on both -stable and -current
and can swap switches too (swap the 3COM and the Kingston)

Thanks
Roger
