It looks like the cxgbe driver doesn't set the DEV_TX_OFFLOAD_MULTI_SEGS
offload capability. However, it looks like sge.c does have support for
sending mbuf chains, e.g. write_sgl(). Is this just an oversight or is
there something fundamentally broken here?

Hi Chas,

Thanks for reporting this. CXGBE does support transmitting mbufs with
multiple segments. However, the corresponding DEV_TX_OFFLOAD_MULTI_SEGS
capability seems to have been missed in the list of supported Tx offload
features. Will send a patch to fix this.

Thanks,
Rahul
