net: macb: move ring size computation to functions

Browse source

[ Upstream commit 92d4256faf ]

The tx/rx ring size calculation is somewhat complex and partially hidden
behind a macro. Move that out of the {RX,TX}_RING_BYTES() macros and
macb_{alloc,free}_consistent() functions into neat separate functions.

In macb_free_consistent(), we drop the size variable and directly call
the size helpers in the arguments list. In macb_alloc_consistent(), we
keep the size variable that is used by netdev_dbg() calls.
