sh_eth: E-DMAC interrupt mask cleanups
Here's a set of 3 patches against DaveM's 'net-next.git' repo. The main goal
of this set is to stop using the bare numbers for the E-DMAC interrupt masks.
[1/3] sh_eth: rename EESIPR bits
[2/3] sh_eth: add missing EESIPR bits
[3/3] sh_eth: stop using bare numbers for EESIPR values
====================
