Bug Description

[Impact]
HiSilicon HNS NIC names are truncated in /proc/interrupts, making it difficult for an admin to associate activity among adapters in the system.

[Test Case]
$ grep enahisic2i0-tx /proc/interrupts | sed 's/.* //'
Without the fix:
  enahisic2i0-tx0
  enahisic2i0-tx1
  [...]
  enahisic2i0-tx8
  enahisic2i0-tx9
  enahisic2i0-tx1
  enahisic2i0-tx1
  enahisic2i0-tx1
  enahisic2i0-tx1
  enahisic2i0-tx1
  enahisic2i0-tx1
With the fix:
  enahisic2i0-tx0
  enahisic2i0-tx1
  enahisic2i0-tx2
  [...]
  enahisic2i0-tx8
  enahisic2i0-tx9
  enahisic2i0-tx10
  enahisic2i0-tx11
  enahisic2i0-tx12
  enahisic2i0-tx13
  enahisic2i0-tx14
  enahisic2i0-tx15

[Regression Risk]
Upstream patch, restricted to a single driver for a system we can directly test.
