This takes "disposable" pages attached to an mbuf, gives them to a user process, and then recycles the user's page. This is only active when ZERO_COPY_SOCKETS is turned on and the kern.ipc.zero_copy.receive sysctl variable is set to 1.uipc_cow.c: Send side zero copy functions. Takes a page written by the user and maps it copy on write and assigns it kernel virtual address space. Removes copy on write mapping once the buffer has been freed by the network stack.uipc_jumbo.c: Jumbo disposable page allocator code. This allocates (optionally) disposable pages for network drivers that want to give the user the option of doing zero copy receive.uipc_socket.c: Add kern.ipc.zero_copy.{send,receive} sysctls that are enabled if ZERO_COPY_SOCKETS is turned on. Add zero copy send support to sosend() -- pages get mapped into the kernel instead of getting copied if they meet size and alignment restrictions.uipc_syscalls.c:Un-staticize some of the sf* functions so that they can be used elsewhere. (uipc_cow.c)if_media.c: In the SIOCGIFMEDIA ioctl in ifmedia_ioctl(), avoid calling malloc() with M_WAITOK. Return an error if the M_NOWAIT malloc fails. The ti(4) driver and the wi(4) driver, at least, call this with a mutex held. This causes witness warnings for 'ifconfig -a' with a wi(4) or ti(4) board in the system. (I've only verified for ti(4)).ip_output.c: Fragment large datagrams so that each segment contains a multiple of PAGE_SIZE amount of data plus headers. This allows the receiver to potentially do page flipping on receives.if_ti.c: Add zero copy receive support to the ti(4) driver. If TI_PRIVATE_JUMBOS is not defined, it now uses the jumbo(9) buffer allocator for jumbo receive buffers. Add a new character device interface for the ti(4) driver for the new debugging interface. This allows (a patched version of) gdb to talk to the Tigon board and debug the firmware. There are also a few additional debugging ioctls available through this interface. Add header splitting support to the ti(4) driver. Tweak some of the default interrupt coalescing parameters to more useful defaults. Add hooks for supporting transmit flow control, but leave it turned off with a comment describing why it is turned off.if_tireg.h: Change the firmware rev to 12.4.11, since we're really at 12.4.11 plus fixes from 12.4.13. Add defines needed for debugging. Remove the ti_stats structure, it is now defined in sys/tiio.h.ti_fw.h: 12.4.11 firmware.ti_fw2.h: 12.4.11 firmware, plus selected fixes from 12.4.13, and my header splitting patches. Revision 12.4.13 doesn't handle 10/100 negotiation properly. (This firmware is the same as what was in the tree previously, with the addition of header splitting support.)sys/jumbo.h: Jumbo buffer allocator interface.sys/mbuf.h: Add a new external mbuf type, EXT_DISPOSABLE, to indicate that the payload buffer can be thrown away / flipped to a userland process.socketvar.h: Add prototype for socow_setup.tiio.h: ioctl interface to the character portion of the ti(4) driver, plus associated structure/type definitions.uio.h: Change prototype for uiomoveco() so that we'll know whether the source page is disposable.ufs_readwrite.c:Update for new prototype of uiomoveco().vm_fault.c: In vm_fault(), check to see whether we need to do a page based copy on write fault.vm_object.c: Add a new function, vm_object_allocate_wait(). This does the same thing that vm_object allocate does, except that it gives the caller the opportunity to specify whether it should wait on the uma_zalloc() of the object structre. This allows vm objects to be allocated while holding a mutex. (Without generating WITNESS warnings.) vm_object_allocate() is implemented as a call to vm_object_allocate_wait() with the malloc flag set to M_WAITOK.vm_object.h: Add prototype for vm_object_allocate_wait().vm_page.c: Add page-based copy on write setup, clear and fault routines.vm_page.h: Add page based COW function prototypes and variable in the vm_page structure.Many thanks to Drew Gallatin, who wrote the zero copy send and receivecode, and to all the other folks who have tested and reviewed this codeover the years.

There are a _lot_ of OEM'edgigabit ethernet adapters out there which use the Alteon chipset sothis driver covers a fair amount of hardware. I know that it works withthe Alteon AceNIC, 3Com 3c985 and Netgear GA620, however it should alsowork with the DEC/Compaq EtherWORKS 1000, Silicon Graphics Gigabitethernet board, NEC Gigabit Ethernet board and maybe even the IBM andand Sun boards. The Netgear board is the cheapest (~$350US) but stillyields fairly good performance.Support is provided for jumbo frames with all adapters (just set theMTU to something larger than 1500 bytes), as well as hardware multicastfiltering and vlan tagging (in conjunction with the vlan support in-current, which I should merge into -stable soon). There are some hooksfor checksum offload support, but they're turned off for now sinceFreeBSD doesn't have an officially sanctioned way to support checksumoffloading (yet).I have not added the 'device ti0' entry to GENERIC since the driverwith all the firmware compiled in is quite large, and it doesn't reallyfit into the category of generic hardware.
