net: hns: Avoid action name truncation
Browse files Browse the repository at this point in the history 
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
