https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D199174 --- Comment #34 from commit-hook@freebsd.org --- A commit references this bug: Author: marius Date: Wed Jan 27 22:31:10 UTC 2016 New revision: 294958 URL: https://svnweb.freebsd.org/changeset/base/294958 Log: Sync the e1000 drivers with what's in head as of r294327, modulo parts that don't apply to stable/10 (driver API, if_inc_counter(), RSS changes etc.) and modulo r287465 (which reportedly breaks igb(4)), i. e. assorted fixes and improvements only: o MFC r267385 (partial): - Don't compare bus_dma map pointers for static DMA allocations against NULL to determine if bus_dmamap_unload() or bus_dmamem_free() should = be called. Instead, check the associated bus and virtual addresses. - Don't clear static DMA maps to NULL. o MFC r284933: Delete the refernce to VLAN handling being disabled by default. This is no longer the case. [1] o MFC r285639: Add an adapter CORE lock in the DDB hook em_dump_queue to avoid WITNESS panic in em_init_locked() while debugging. o MFC r285879: - Remove unused txd_saved. - Intialize txd_upper, txd_lower and txd_used at declaration. o MFC r286162: Free mbufs when busdma loading fails. o MFC r286829: Add capability to disable CRC stripping as it breaks IPMI/BMC capabilit= ies on certain adatpers. [2] o MFC r286831: [3] - 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@ - Set if_hw_tsomax, if_hw_tsomaxsegcount and 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 interrup= ts and not just a hardcoded define of values. o MFC r286832: e1000/if_lem.c bump to 1.1.0 o MFC r286833: Bump all copywrite dates to 2015. o MFC r287112: Style/whitespace cleanup in shared/common code. o MFC r293331: - Switch em(4) to the extended RX descriptor format. - Split rxbuffer and txbuffer apart to support the new RX descriptor format structures. Move rxbuffer manipulation to em_setup_rxdesc() to unify the new behavior changes. - Add a RSSKEYLEN macro for help in generating the RSSKEY data structur= es in the card. - Change em_receive_checksum() to process the new rxdescriptor format status bit. o MFC r293332: Disable the reuse of checksum offload context descriptors in the case of multiple queues in em(4). Document errata in the code. o MFC r293854: Given that em(4), lem(4) and igb(4) hardware doesn't require the alignment guarantees provided by m_defrag(9), use m_collapse(9) instead for performance reasons. While at it, sanitize the statistics softc members, i. e. retire unused ones and add SYSCTL nodes missing for actually used ones.
