AFAIK BCM5716 is a gigabit ethernet and bce(4) supports the
controller.  bce(4) lacks multi-queue support but all other
hardware features are supported.  Enabling multi-queue for both
bce(4) and bge(4) is one of my TODO list but I couldn't find spare
time to do that.

As John said, bxe(4) supports Broadcom's 10G controllers, BCM5771x.
The driver supports all hardware features you mentioned(including
multi-queue through RSS/TSS).  Unlike most other 10G controllers,
these controllers support hardware based true LRO which would
outperform software based implementation.  bxe(4) is not available
on 8.x yet.
