From 9e9c1e7d025df314008fa28581b7ab7f7fcf6f20 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Fri, 27 May 2011 04:51:54 +0000 Subject: atm: expose ATM device index in sysfs commit e7a46b4d0839c2a3aa2e0ae0b145f293f6738498 upstream. It's currently exposed only through /proc which, besides requiring screen-scraping, doesn't allow userspace to distinguish between two identical ATM adapters with different ATM indexes. The ATM device index is required when using PPPoATM on a system with multiple ATM adapters. Signed-off-by: Dan Williams Reviewed-by: Eric Dumazet Tested-by: David Woodhouse Signed-off-by: David S.
