Subject: [PATCH net-next v8 17/28] zinc: Poly1305 MIPS32r2 and MIPS64 implementations
This MIPS32r2 implementation comes from René van Dorst and me and
results in a nice speedup on the usual OpenWRT targets. The MIPS64
implementation from Andy Polyakov ported here results in a nice speedup
on commodity Octeon hardware, and has been modified slightly from the
original:
- The function names have been renamed to fit kernel conventions.
- A comment has been added.
