[ Upstream commit 4dc93fcf0b95dc3fda4db917effae31fbb8ad2a8 ]
On the RAH registers there are semantic differences on the meaning of the "queue" parameter for traffic steering depending on the controller model: there is the 82575 meaning, which "queue" means a RX Hardware Queue, and the i350 meaning, where it is a reception pool.
The previous behaviour was having no effect for i210 based controllers because the QSEL bit of the RAH register wasn't being set.
This patch separates the condition in discrete cases, so the different handling is clearer.
