Hi Dave,
Here's V1 of this batch of mlx4 driver updates for 3.10, mostly DCB related.
Series done against the net-next tree as of commit a210576c "Merge
git://git.kernel.org/pub/scm/linux/kernel/git/davem/net"
changes from V0:
- in patch #2 advertize getdcbx/setdcbx callbacks also for devices that support only PFC
- per feedback from John, dropeed patch #3 which turned to be work-around for user space
bug in open-lldp. John posted a user space patch to fix the bug
- per feedback from John, added small a patch under which we advertize DCB_CAP_DCBX_HOST in getdcbx
Or.
Or Gerlitz (3):
net/mlx4_core: Added proper description for two device capabilities
net/mlx4_en: Enable DCB ETS ops only when supported by the firmware
net/mlx4_en: Advertize DCB_CAP_DCBX_HOST in getdcbx

Enable the DCB ETS ops only when supported by the firmware. For older firmware/cards
which don't support ETS, advertize only PFC DCB ops.

When our getdcbx entry is called, DCB_CAP_DCBX_HOST should be advertized too.
