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 <kaia...@gmail.com>, who helped in debugging
and testing the patch.
