[PATCH v3 net 0/7] mvneta fixes for SMP

[Gregory CLEMENT <gregory.clement@free-electrons.com>]

Hi,

Following this bug report:
http://thread.gmane.org/gmane.linux.ports.arm.kernel/468173 and the
suggestions from Russell King, I reviewed all the code involving
multi-CPU. It ended with this series of patches which should improve
the stability of the driver.

During my test I found another bug which is fixed by new patch (the
second one of this new version of the series)

The two first patches fix real bugs, the others fix potential issues
in the driver.

Thanks,

Gregory
