| Subject: net: hns: Avoid action name truncation |
| |
| From: dann frazier <dann.frazier@canonical.com> |
| |
| [ Upstream commit f4ea89110df237da6fbcaab76af431e85f07d904 ] |
| |
| When longer interface names are used, the action names exposed in |
| /proc/interrupts and /proc/irq/* maybe truncated. For example, when |
| using the predictable name algorithm in systemd on a HiSilicon D05, |
| I see: |
| |
| ubuntu@d05-3:~$ grep enahisic2i0-tx /proc/interrupts | sed 's/.* //' |
| enahisic2i0-tx0 |
| enahisic2i0-tx1 |
| [...] |
| enahisic2i0-tx8 |
| enahisic2i0-tx9 |
| enahisic2i0-tx1 |
| enahisic2i0-tx1 |
| enahisic2i0-tx1 |
| enahisic2i0-tx1 |
| enahisic2i0-tx1 |
| enahisic2i0-tx1 |
| |
| Increase the max ring name length to allow for an interface name |
| of IFNAMSIZE. After this change, I now see: |
| |
| $ grep enahisic2i0-tx /proc/interrupts | sed 's/.* //' |
| enahisic2i0-tx0 |
| enahisic2i0-tx1 |
| enahisic2i0-tx2 |
| [...] |
| enahisic2i0-tx8 |
| enahisic2i0-tx9 |
| enahisic2i0-tx10 |
| enahisic2i0-tx11 |
| enahisic2i0-tx12 |
| enahisic2i0-tx13 |
| enahisic2i0-tx14 |
| enahisic2i0-tx15 |
