| Subject: atm: expose ATM device index in sysfs |
| |
| From: Dan Williams <dcbw@redhat.com> |
| |
| 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. |
