Missing fix for fxp driver (FreeBSD 6.x)

[Fabien Thomas]

Sorry for the noise...
I've made a mistake with my local patch vs cvsweb vs commit info that  
seems to fix the same problem but with another code.

If i've to rewrite my initial mail:

The fxp deadlock (fixed on head by this commit http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/fxp/if_fxp.c.diff?r1=1.266;r2=1.267)
can be easily reproduced and maybe can be MFC in 6.4 and 7.1 ?

When the interface is in deadlock the only way to recover is to do a  
ifconfig up.
