All we have to do is make sure it is really partof the RX frame, that it is valid, and if the respective bits are set.Also do not forget to set the (dummy) csum_data as otherwise upperlayers will just be cranky. An artefact of the past which likelyshould disappear.PR: 292006Reviewed by: bz, tuexenTested by: bz, tuexenApproved by: tuexenObtained from: bz (initial version, D55320)MFC after: 3 daysSponsored by: Traverse Technologies (providing Ten64 HW for testing)Differential Revision: https://reviews.freebsd.org/D56383 List of files: /freebsd/sys/dev/dpaa2/dpaa2_frame.c Mon, 13 Apr 2026 14:46:49 +0200 Dmitry Salychev <dsl@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/dev/dpaa2/dpaa2_frame.c#8e994533806d8aa0ae4582a52d811ede2b19bb26 dpaa2: Extract frame-specific routines to dpaa2_frame.[h,c]As soon as we need information from the hardware frame annotation tomake sure that checksums of the ingress frames were verified by theDPAA2 HW, I've decided to make a preparation and extracted all of theframe related routines into the separate dpaa2_frame.[h,c] along withsome clean up and improvements, e.g. no more dpaa2_fa, but dpaa2_swaand dpaa2_hwa structures to describe software and hardware frameannotations respectively, dpaa2_fa_get_swa/dpaa2_fa_get_hwa to obtainthose annotations from the frame descriptor. The next step is toimplement dpaa2_fa_get_hwa.PR: 292006Approved by: tuexenMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D56315 List of files: /freebsd/sys/dev/dpaa2/dpaa2_frame.c Sun, 25 Jan 2026 17:53:57 +0100 Dmitry Salychev <dsl@FreeBSD.org>
