- Allow mlx4 devices to switch between Ethernet and Infiniband: - Fix sysfs attribute handling by using sysctl_handle_string() and properly handling trailing newlines in attribute values. - Remove check forbidding requests that would result in one port being set to Ethernet and the subsequent port being set to IB. - Avoid trashing IP fragments by correctly managing hardware checksumming. - Fix panics when downing or unloading the mlx4 driver.

Build tested with make universe. r237263: - Updated TOE support in the kernel. ... r237563: Fix clang warning when compiling iw_cxgb. r239511: Correctly handle the case where an inp has already been dropped by the time the TOE driver reports that an active open failed. toe_connect_failed is supposed to handle this but it should be provided the inpcb instead of the tcpcb which may no longer be around. r243603: Make sure that tcp_timer_activate() correctly sees TCP_OFFLOAD (or not). r245915: Heed SO_NO_OFFLOAD. r245916: Teach toe_4tuple_check() to deal with IPv6 4-tuples too. r245919: Add TCP_OFFLOAD hook in syncache_respond for IPv6 too, just like the one that exists for IPv4. r245921: There is no need to call into the TOE driver twice in pru_rcvd (tod_rcvd and then tod_output right after that). r245922: Avoid NULL dereference in nd6_storelladdr when no mbuf is provided. It is called this way from a couple of places in the OFED code. (toecore calls it too but that's going to change shortly). r245924: Move lle_event to if_llatbl.h lle_event replaced arp_update_event after the ARP rewrite and ended up in if_ether.h simply because arp_update_event used to be there too. IPv6 neighbor discovery is going to grow lle_event support and this is a good time to move it to if_llatbl.h. The two in-tree consumers of this event - OFED and toecore - are not affected. r245925: Generate lle_event in the IPv6 neighbor discovery code too. r245932: Teach toe_l2_resolve to resolve IPv6 destinations too. r245934: Add checks for SO_NO_OFFLOAD in a couple of places that I missed earlier in r245915.

Store a reference to the vnode associated with a file descriptor in the linux_file structure and use it instead of directly accessing td_fpop when destroying the linux_file structure. The td_fpop pointer is not valid when a cdevpriv destructor is run, and the type-specific close method has already been called, so f_vnode may not be valid (and the vnode might have been recycled without our own reference).

According to the documentation, on Linux, cancel_delayed_work() does not do drain (flush_workqueue() in Linux terms) but instead returns true if the work was removed before it is run, or false otherwise. Simulate this by removing the taskqueue_drain() and return the value derived from taskqueue_cancel()'s return value. This would solve a witness warning caused by calling taskqueue_drain() with a non-sleepable lock held, like: taskqueue_drain with the following non-sleepable locks held: exclusive rw lle (lle) r = 0 (0xfffffe001450b410) locked @ /usr/src/sys/netinet/in.c:1484 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xffffff848d4f7690 kdb_backtrace() at kdb_backtrace+0x39/frame 0xffffff848d4f7740 witness_warn() at witness_warn+0x4a8/frame 0xffffff848d4f7800 taskqueue_drain() at taskqueue_drain+0x3a/frame 0xffffff848d4f7840 set_timeout() at set_timeout+0x4a/frame 0xffffff848d4f7860 netevent_callback() at netevent_callback+0x16/frame 0xffffff848d4f7870 arpintr() at arpintr+0x9b5/frame 0xffffff848d4f7930 This do not affect kernel without OFED compiled in.

Redo r242842, now actually fixing the warnings, as follows: - In sys/ofed/drivers/infiniband/core/cma.c, an enum struct member is interpreted as an int, so cast it to an int. - In sys/ofed/drivers/infiniband/core/ud_header.c, initialize the packet_length variable in ib_ud_header_init(), to prevent undefined behaviour. - In sys/ofed/drivers/infiniband/ulp/sdp/sdp_rx.c, call rdma_notify() with the correct enum type and value. - In sys/ofed/include/linux/pci.h, change the PCI_DEVICE and PCI_VDEVICE macros to use C99 struct initializers, so additional members can be overridden.

Align the PCI Express #defines with the style used for the PCI-X #defines. This has the advantage that it makes the names more compact, and also allows us to correct the non-uniform naming of the PCIM_LINK_* defines, making them all consistent amongst themselves. This is a mostly mechanical rename: s/PCIR_EXPRESS_/PCIER_/g s/PCIM_EXP_/PCIEM_/g s/PCIM_LINK_/PCIEM_LINK_/g In this MFC, #defines have been added for the old names to assist out-of-tree drivers.
