Subject: [PATCH] net/vmxnet3: fix MAC address set

[ upstream commit 66db172f2636a1634b3e8e73afb76968d35acc5e ]

Updated vmxnet3_mac_addr_set() to store the newly set MAC address.
Modified vmxnet3_write_mac() so the h/w is updated in an endian
neutral manner.

Fixes: 139f39a97859 ("vmxnet3: support setting MAC address")
