* Move ethernet VLAN tags from mtags to its own mbuf packet header fieldAndre Oppermann2006-09-171-7/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | m_pkthdr.ether_vlan. The presence of the M_VLANTAG flag on the mbuf signifies the presence and validity of its content. Drivers that support hardware VLAN tag stripping fill in the received VLAN tag (containing both vlan and priority information) into the ether_vtag mbuf packet header field: m->m_pkthdr.ether_vtag = vlan_id; /* ntohs()? */ m->m_flags |= M_VLANTAG; to mark the packet m with the specified VLAN tag. On output the driver should check the mbuf for the M_VLANTAG flag to see if a VLAN tag is present and valid: if (m->m_flags & M_VLANTAG) { ... = m->m_pkthdr.ether_vtag; /* htons()? */ ... pass tag to hardware ... } VLAN tags are stored in host byte order. Byte swapping may be necessary. (Note: This driver conversion was mechanic and did not add or remove any byte swapping in the drivers.) Remove zone_mtag_vlan UMA zone and MTAG_VLAN definition. No more tag memory allocation have to be done. Reviewed by: thompsa, yar Sponsored by: TCP/IP Optimization Fundraise 2005 Notes: svn path=/head/; revision=162375

* - Tx side bus_dmamap_load_mbuf_sg(9) support. This reduces bookkeepingPyun YongHyeon2006-01-032-168/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | requiried to keep consistent softc state before/after callback function invocation and supposed to be sligntly faster than previous one as it wouldn't incur callback overhead. With this change callback function was gone. - Decrease TI_MAXTXSEGS to 32 from 128. It seems that most mbuf chain length is less than 32 and it would be re-packed with m_defrag(9) if its chain length is larger than TI_MAXTXSEGS. This would protect ti(4) against possible kernel stack overflow when txsegs[] is put on stack. Alternatively, we can embed the txsegs[] into softc. However, that would waste memory and make Tx/Rx speration hard when we want to sperate Tx/Rx handlers to optimize locking. - Fix dma map tracking used in Tx path. Previously it used the dma map of the last mbuf chain in ti_txeof() which was incorrect as ti(4) used dma map of the first mbuf chain when it loads a mbuf chain with bus_dmamap_load_mbuf(9). Correct the bug by introducing queues that keep track of active/inactive dma maps/mbuf chain. - Use ti_txcnt to check whether driver need to set watchdog timer instead of blidnly clearing the timer in ti_txeof(). - Remove the 3rd arg. of ti_encap(). Since ti(4) now caches the last descriptor index(ti_tx_saved_prodidx) used in Tx there is no need to pass it as a fuction arg. - Change data type of producer/consumer index to int from u_int16_t in order to remove implicit type conversions in Tx/Rx handlers. - Check interface queue before getting a mbuf chain to reduce locking overhead. - Check number of available Tx descriptores to be 16 or higher in ti_start(). This wouldn't protect Tx descriptor shortage but it would reduce number of bus_dmamap_unload(9) calls in ti_encap() when we are about to running out of Tx descriptors. - Command NIC to send packets ony when the driver really has packets enqueued. Previously it always set TI_MB_SENDPROD_IDX which would command NIC to DMA Tx descriptors into NIC local memory regardless of Tx descriptor changes.

* Fix the Tigon I/II driver to support 64-bit DMA. In the process, convert itScott Long2005-12-142-99/+347
| | | | | | | | | | | | | | | | | | | | | | | to use busdma. Unlike most of the other drivers, but similar to the if_em driver, pre-allocate the dmamaps at init time instead of allocating them on the fly when descriptors need to be filled. This isn't ideal right now because a map is allocated for every descriptor slot in the tx, rx, mini, and jumbo rings (which is a lot!) in order to simplify the bookkeeping, even though the driver might support filling only a subset of those slots. Luckily, maps are typically NULL on i386 and amd64, so the cost isn't very high. It could be an issue with sparc64, but the driver isn't endian clean either, and that is a much bigger problem to solve first. Note that jumbo frame support is under-tested, and I'm not even sure if it till really works correctly given the evil VM magic that is does. The changes here attempt to preserve the existing semanitcs. Thanks to Martin Nillson for contributing the Netgear card for this work. MFC-After: 3 weeks Notes: svn path=/head/; revision=153396

| | | | | | | | | | | | | | | | | | | | | | | 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.
