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.
