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
