Subject: atm: expose ATM device index in sysfs
From: Dan Williams <[email protected]>
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.
