--- Comment #11 from commit-h...@freebsd.org --- A commit references this bug: Author: pkelsey Date: Sat Mar 14 20:08:04 UTC 2020 New revision: 359000 URL: https://svnweb.freebsd.org/changeset/base/359000 Log: Fix if_vmx receive checksum offload bug and harden against the device skipping receive descriptors This fixes a bug where the checksum offload status of received packets was being taken from the first descriptor instead of the last, which affected LRO packets. The driver has been hardened against the device skipping receive descriptors, although it is not believed that this can occur given the way this implementation configures the receive rings. Additionally, for packets received with the error indicator set, the driver now forces the length of all fragments in that packet to zero prior to passing it to iflib. Such packets should wind up being discarded at some point in the stack anyway, but this removes any questions by killing them in the driver. Counters have been added (and exposed via sysctls) for skipped receive descriptors, zero-length packets received, and packets received with the error indicator set so that these conditions can be easily observed in the field.
