carl9170: revamp carl9170_tx_prepare
David Miller complained about the driver's excessive use
of variables in __packed structs. While I did not fully
agree with his sole "performance" argument on all accounts.
I do see some room for improvement in hot-paths on
architectures without an efficient access to unaligned
elements.
This first patch (dare I say?) optimizes an important tx
hot-path in the driver: carl9170_tx_prepare.
