tg3: Move per-int tx members to a per-int struct
Matt Carlson [Fri, 28 Aug 2009 14:03:21 +0000 (14:03 +0000)]
This patch moves the tx_prod, tx_cons, tx_pending, tx_ring, and
tx_buffers transmit ring device members to a per-interrupt structure.
It also adds a new transmit producer mailbox member (prodmbox) and
converts the code to use it rather than a preprocessor constant.
