--- Comment #26 from commit-h...@freebsd.org --- A commit references this bug: Author: vmaffione Date: Mon Aug 10 17:53:10 UTC 2020 New revision: 364085 URL: https://svnweb.freebsd.org/changeset/base/364085 Log: MFC r363378 iflib: initialize netmap with the correct number of descriptors In case the network device has a RX or TX control queue, the correct number of TX/RX descriptors is contained in the second entry of the isc_ntxd (or isc_nrxd) array, rather than in the first entry. This case is correctly handled by iflib_device_register() and iflib_pseudo_register(), but not by iflib_netmap_attach(). If the first entry is larger than the second, this can result in a panic. This change fixes the bug by introducing two helper functions that also lead to some code simplification.
