https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=199174 --- Comment #33 from commit-hook@freebsd.org --- A commit references this bug: Author: sbruno Date: Sun Aug 16 19:43:45 UTC 2015 New revision: 286831 URL: https://svnweb.freebsd.org/changeset/base/286831 Log: Increase EM_MAX_SCATTER to 64 such that the size of em_xmit()::segs[EM_MAX_SCATTER] doesn't get overrun by things like NFS that can and do shove more than 32 segs when being used with em(4) and TSO4. Update tso handling code in em_xmit() with update from jhb@ in email thread: https://lists.freebsd.org/pipermail/freebsd-net/2014-July/039306.html set ifp->if_hw_tsomax, ifp->if_hw_tsomaxsegcount & ifp->if_hw_tsomaxsegsize to appropriate values. Define a TSO workaround "magic" number of 4 that is used to avoid an alignment issue in hardware. Change a couple of integer values that were used as booleans to actual bool types. Ensure that em_enable_intr() enables the appropriate mask of interrupts and not just a hardcoded define of values.
