https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=188990 --- Comment #14 from Bhavesh Davda <bhavesh.davda@gmail.com> --- (In reply to Roger Pau Monné from comment #8) I looked at the proposed patch to the netfront driver, and think this introduces a semantic mismatch between the meaning of the 'NETRXF_data_validated' rx->flag between the netback driver in dom-0 and the netfront driver in the FreeBSD dom-U. Basically 'NETRXF_data_validated' says (from the equivalent CHECKSUM_UNNECESSARY Linux skbuff flag that the Linux dom-0 netback driver uses for this): * CHECKSUM_UNNECESSARY: * * The hardware you're dealing with doesn't calculate the full checksum * (as in CHECKSUM_COMPLETE), but it does parse headers and verify checksums * for specific protocols. For such packets it will set CHECKSUM_UNNECESSARY * if their checksums are okay. -- You are receiving this mail because: You are the assignee for the bug.
