Marius Strobl a8376f70e7 Do as the Linux tg3 driver does and enable MSI support also 
for the BCM5714 revision A0 when in a multi-port configuration
and unconditionally for the remainder of the class of BCM575X
and beyond chips.
This was prodded by mav and is based on a suggestion and a
patch submitted by jhb.

* Broadcom BCM570x family gigabit ethernet driver for FreeBSD.
*
* The Broadcom BCM5700 is based on technology originally developed by
* Alteon Networks as part of the Tigon I and Tigon II gigabit ethernet
* MAC chips. The BCM5700, sometimes refered to as the Tigon III, has
* two on-board MIPS R4000 CPUs and can have as much as 16MB of external
* SSRAM. The BCM5700 supports TCP, UDP and IP checksum offload, jumbo
* frames, highly configurable RX filtering, and 16 RX and TX queues
* (which, along with RX filter rules, can be used for QOS applications).
* Other features, such as TCP segmentation, may be available as part
* of value-added firmware updates. Unlike the Tigon I and Tigon II,
* firmware images can be stored in hardware and need not be compiled
* into the driver.
*
* The BCM5700 supports the PCI v2.2 and PCI-X v1.0 standards, and will
* function in a 32-bit/64-bit 33/66Mhz bus, or a 64-bit/133Mhz bus.
*
* The BCM5701 is a single-chip solution incorporating both the BCM5700
* MAC and a BCM5401 10/100/1000 PHY. Unlike the BCM5700, the BCM5701
* does not support external SSRAM.
*
* Broadcom also produces a variation of the BCM5700 under the "Altima"
* brand name, which is functionally similar but lacks PCI-X support.
*
* Without external SSRAM, you can only have at most 4 TX rings,
* and the use of the mini RX ring is disabled. This seems to imply
* that these features are simply not available on the BCM5701. As a
* result, this driver does not implement any support for the mini RX
* ring.
