Subject: [BUG 2.5.67 (and probably earlier)] /proc/dev/net doesnt show all net devices
Date: Tue, 29 Apr 2003 14:34:18 +0200	[thread overview]
Message-ID: <200304291434.18272.linux@borntraeger.net> (raw)

Summary: /proc/net/devices doesnt show all devices using cat. With dd all are 
available.

I tested a kernels prior to 
http://linus.bkbits.net:8080/linux-2.5/cset@1.797.156.3
and it doesnt seem to have this problem.

If I do a 
& cat /proc/net/dev

I get net devices till eth1, but eth2 and hsi0 are available nevertheless.
but if I do a 

& dd if=/proc/net/dev bs=4096
