 Hello!

 The driver we use with our routers is Beckers 0.91 and 0.91g with code
 for fast switching, hw_flowcontrol 2 variants, skb recycling in FS,
 tulip chip info plus statistics in /proc. And a way of giving options
 via ioctl so an interface MII-media can be changed without stopping all 
 interfaces.
 Also a fix for forcing the transceiver chips on D-LINK 4-port boards into 
 different media types.
 
 As I did mention this reflects a lot of experimentation. But we use only 
 with handful of boards, And as said we don't use FS in production we
 still have enough CPU for "Normal path".

 I have no idea if anything is of interest and/or has quality enough to 
 be used with any Linux distribution. BTW SMP does not work.

 Maybe HW_FLOWCONTROL and CONFIG_NET_HW_FLOWCONTROL can be merged in if
 there is any interest. This was the state in the 2.1 kernels.
