[dpdk-dev] [PATCH v3] cxgbe: report 100G link speed capability for Chelsio T6 adapters

[Martin Weiser]

These adapters support 100G link speed but the speed_capa bitmask in the
device info did not reflect that.

Thanks for the patch.  However, not all Chelsio T6 adapters support
10G/40G/100G link speeds at the same time.  I have a patch to report
the supported link speeds correctly and is currently undergoing testing.
I will submit the patch very soon.

Thanks,
Rahul
