Author: arybchik Date: Wed Jan 13 06:37:45 2016 New Revision: 293806 URL: https://svnweb.freebsd.org/changeset/base/293806 Log: sfxge: remove unused common code EFSYS_OPT_RX_HDR_SPLIT The EFSYS_OPT_RX_HDR_SPLIT optional feature in the common code implemented the Lookahead Split feature of Windows. This split received packets at a preconfigured byte offset, and delivered the header and payload portions to separate receive queues. Now the common code interface has no callers, so remove it. Note that this should not be confused with the Header Data Split feature of Windows, which splits packets at a header boundary.
