Series staging: r8188eu: some more xmit cleanups |

Commit Message

Martin Kaiser Jan. 23, 2023, 8:53 p.m. UTC 
  struct xmit_priv contains a pointer to an array of struct hw_xmit entries.
xmit_priv's (ill-named) hwxmit_entry component stores the size of this
array, i.e. the number of hw_xmit entries that are used.

The array size is constant, it's initialised to HWXMIT_ENTRY and never
updated. Simplify the code accordingly. Remove hwxmit_entry, do not pass
the array size as a function parameter and use HWXMIT_ENTRY in the code
that handles the array.
