Author: tuexen Date: Wed May 14 19:00:01 2014 New Revision: 266081 URL: http://svnweb.freebsd.org/changeset/base/266081 Log: MFC r263096: Put the offset of the CRC32C in csum_data instead of 0. The virtio driver needs the offset to be stored in csum_data, like in the case for UDP and TCP. The virtio problem was reported by Niu Zhixiong <kaiaixi@gmail.com>, who helped in debugging and testing the patch.
