8 | commit e7a46b4d0839c2a3aa2e0ae0b145f293f6738498 upstream. | |
9 | ||
10 | It's currently exposed only through /proc which, besides requiring | |
11 | screen-scraping, doesn't allow userspace to distinguish between two | |
12 | identical ATM adapters with different ATM indexes. The ATM device index | |
13 | is required when using PPPoATM on a system with multiple ATM adapters. | |
