| | | | | | | | | | | | | | | | | IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field. Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-106-114/+122
| | | | | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

| | | | | | | | | | | are now in the header of the external buffer itself which allows us to manipulate them in the free routine without having to lock the softc structure or the free list. To get space for these flags the chunk number is reduced to 8 bit which amounts to a maximum of 256 chunks per allocated page. This restriction is now enforced by a CTASSERT.

* Allow sending of more than one raw cell from a single mbuf. Only theHartmut Brandt2003-10-291-8/+11
| | | | | | | | | | | | | | | very first cell in the mbuf should have a cell header word (of which everything except the payload type and the CLP bit is ignored). All other cells should be 48 byte and get the same header as the first cell. This fixes a problem with sending more than 120000 raw cells/sec through an HE155. The card seems to need 2 cell times to DMA the transmit buffer ready queue entry and the transmit buffer descriptor so at 1/3 the link rate the transmit buffer ready queue starts to fill up. Even with this patch it's obviously impossible to send raw cells at link rate. Notes: svn path=/head/; revision=121687

Note, that we could even further delay the allocation of the mbuf until we know, that we need it (there are no receive errors and the connection is open). This will be done in a later commit.

Update the head pointer of the receive buffer pool queue even when we could not supply a buffer to the chip. Otherwise the chip will not re-interrupt us for another try. A better strategy would probably be to remember this condition and to supply buffers without an interrupt as soon as buffers get available. Notes: svn path=/head/; revision=121617

We need to be sure that our packets are kept in-sequence (that's how ATM is supposed to work) and therefor use BUS_DMA_NOWAIT in all calls to bus_dmamap_load. For memory allocated with bus_dmamem_alloc the use of anything other than NULL arguments for the locking is anyway bogus because this memory never should need bouncing and hence the load should never be defered. Allow the receipt of OAM and RM cells on raw connections. Caveat: it seems that RM cells are still processed by the hardware even when we open the connection as UBR.

* Mega busdma API commit.Scott Long2003-07-011-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg. Lockfunc allows a driver to provide a function for managing its locking semantics while using busdma. At the moment, this is used for the asynchronous busdma_swi and callback mechanism. Two lockfunc implementations are provided: busdma_lock_mutex() performs standard mutex operations on the mutex that is specified from lockfuncarg. dftl_lock() is a panic implementation and is defaulted to when NULL, NULL are passed to bus_dma_tag_create(). The only time that NULL, NULL should ever be used is when the driver ensures that bus_dmamap_load() will not be deferred. Drivers that do not provide their own locking can pass busdma_lock_mutex,&Giant args in order to preserve the former behaviour. sparc64 and powerpc do not provide real busdma_swi functions, so this is largely a noop on those platforms. The busdma_swi on is64 is not properly locked yet, so warnings will be emitted on this platform when busdma callback deferrals happen. If anyone gets panics or warnings from dflt_lock() being called, please let me know right away. Reviewed by: tmm, gibbs Notes: svn path=/head/; revision=117126
