-stable review patch. If anyone has any objections, please let us know.
------------------
There's a bug in the driver that only initializes half of the context
memory on the 5708. Surprisingly, this works most of the time except
for some occasional netdev watchdogs when sending a lot of 64-byte
packets. This fix is to add the missing code to initialize the 2nd
half of the context memory.
Update version to 1.5.8.2.
