The DM9000_NSR register contains a copy of the internal PHY's link status which we can use to determine if the link is up or down. This eliminates the more costly (and sleeping) PHY read when using the DM9000's own PHY. Signed-off-by:

Remove the now extraneous checks in dm9000_release_board() now that the two-resource case is removed. Also remove the check on pdev->num_resources, as we check the return data from platform_get_resource() to ensure we have not only the right number but the right type of resources as well.

Add support for both the DM9000A and DM9000B versions of the DM9000 networking chip. This includes adding support for the Link-Change IRQ which is used instead of polling the PHY every 2 seconds. Signed-off-by:

The dm9000 driver accepts either 2 or 3 resources to describe the platform devices. The 2 resources case abuses the ioresource mechanism by passing ioremap()ed memory through the platform device resources. This patch removes converts boards that were using it to the 3 resources scheme. CC: Bryan Wu <cooloney@kernel.org> Signed-off-by:

The TPA stands for Transparent Packet Aggregation. When enabled, the FW aggregate in-order TCP packets according to the 4-tuple match and sends 1 big packet to the driver. This packet is stored on an SGL in which each SGE is 1 page. The FW also implements a timeout algorithm and it honors all TCP flag, including the push flag as a trigger to halt aggregation. After receiving Ben Hutchings comments, we also added ethtool support, so now, thanks to Ben's patch, when forwarding is enabled, our aggregation is turned off using the LRO flags. Signed-off-by:

Supporting the 57711 and 57711E - refers to in the code as E1H. The 57710 is referred to as E1. To support the new members in the family, the bnx2x structure was divided to 3 parts: common, port and function. These changes caused some rearrangement in the bnx2x.h file. A set of accessories macros were added to make access to the bnx2x structure more readable Signed-off-by:

This new initialization code supports the 57711 HW. It also supports the emulation and FPGA for the 57711 and 57710 initializations values (very small amount of code which is very helpful in the lab - less than 30 lines). The initialization is done via DMAE after the DMAE block is ready - before it is ready, some of the initialization is done via PCI configuration transactions (referred to as indirect write). A mutex to protect the DMAE from being overlapped was added. There are few new registers which needs to be initialized by SW - the full comment for those registers is added to the register file. A place holder for the 57711 (referred to as E1H) microcode was added- the microcode itself is too big and it is split over the following 4 patches Signed-off-by:

New Link code: Moving all the link related code (including the calculations, the initialization of the MAC and PHY and the external PHY's code) into a separated file. The changes from the code that used to be part of bnx2x.c (now called bnx2x_main.c) are: - Using separate structures for link inputs and link outputs to clearly identify what was configured and what is the outcome - Adding code to read external PHY FW version and print it as part of ethtool -i - Adding code to upgrade external PHY FW from ethtool -E with special magic number - Changing the link down indication to ERR level - Adding a lock on all PHY access to prevent an interrupt and setting changes to overlap - Adding support for emulation and FPGA (small chunk of code that really helps in the lab) - Adding support for 1G on BCM8706 PHY - Adding clear debug print incase of fan failure (the PHY type is now "failure") Signed-off-by:

Use the same MSI-X handler to schedule NAPI. Change the dev_instance void pointer to the bnx2_napi struct instead so we can have the proper context for each MSI-X vector. Add a new bnx2_poll_msix() that is optimized for handling MSI-X NAPI polling of rx/tx work only. Remove the old bnx2_tx_poll() that is no longer needed. Each MSI-X vector handles 1 tx and 1 rx ring. The first vector handles link events as well. Signed-off-by:

Add hw_tx_cons_ptr and hw_rx_cons_ptr to speed up the retreival of the tx and rx consumer index, since the MSI-X and default status blocks have different structures. Combine status_blk and status_blk_msix into a union. We'll only use one type of status block for each vector. Separate the code to detect more rx and tx work from the code to detect link related work. Signed-off-by:

In preparation for multi-ring support, tx ring variables are now put in a separate bnx2_tx_ring_info struct. Multi tx ring will not be enabled until it is fully supported by the stack. Only 1 tx ring will be used at the moment. The functions to allocate/free tx memory and to initialize tx rings are now modified to handle multiple rings. Signed-off-by:

Large Receive Offload (LRO) is only appropriate for packets that are destined for the host, and should be disabled if received packets may be forwarded. It can also confuse the GSO on output. Add dev_disable_lro() function which uses the appropriate ethtool ops to disable LRO if enabled. Add calls to dev_disable_lro() in br_add_if() and functions that enable IPv4 and IPv6 forwarding.

RFC 4960, Section 11.4. Protection of Non-SCTP-Capable Hosts When an SCTP stack receives a packet containing multiple control or DATA chunks and the processing of the packet requires the sending of multiple chunks in response, the sender of the response chunk(s) MUST NOT send more than one packet. If bundling is supported, multiple response chunks that fit into a single packet MAY be bundled together into one single response packet. If bundling is not supported, then the sender MUST NOT send more than one response chunk and MUST discard all other responses. Note that this rule does NOT apply to a SACK chunk, since a SACK chunk is, in itself, a response to DATA and a SACK does not require a response of more DATA. We implement this by not servicing our outqueue until we reach the end of the packet. This enables maximum bundling. We also identify 'response' chunks and make sure that we only send 1 packet when sending such chunks. Signed-off-by:

This patch add to validate initiate tag and chunk type if verification tag is 0 when handling ICMP message. RFC 4960, Appendix C. ICMP Handling ICMP6) An implementation MUST validate that the Verification Tag contained in the ICMP message matches the Verification Tag of the peer. If the Verification Tag is not 0 and does NOT match, discard the ICMP message. If it is 0 and the ICMP message contains enough bytes to verify that the chunk type is an INIT chunk and that the Initiate Tag matches the tag of the peer, continue with ICMP7. If the ICMP message is too short or the chunk type or the Initiate Tag does not match, silently discard the packet. Signed-off-by:

genetlink has a circular locking dependency when dumping the registered families: - dump start: genl_rcv() : take genl_mutex genl_rcv_msg() : call netlink_dump_start() while holding genl_mutex netlink_dump_start(), netlink_dump() : take nlk->cb_mutex ctrl_dumpfamily() : try to detect this case and not take genl_mutex a second time - dump continuance: netlink_rcv() : call netlink_dump netlink_dump : take nlk->cb_mutex ctrl_dumpfamily() : take genl_mutex Register genl_lock as callback mutex with netlink to fix this. This slightly widens an already existing module unload race, the genl ops used during the dump might go away when the module is unloaded. Thomas Graf is working on a seperate fix for this.

Max of promiscuity and allmulti plus positive @inc can cause overflow. Fox example: when allmulti=0xFFFFFFFF, any caller give dev_set_allmulti() a positive @inc will cause allmulti be off. This is not what we want, though it's rare case. The fix is that only negative @inc will cause allmulti or promiscuity be off and when any caller makes the counters touch the roof, we return error. Change of v2: Change void function dev_set_promiscuity/allmulti to return int. So callers can get the overflow error. Caller's fix will be done later. Change of v3: 1. Since we return error to caller, we don't need to print KERN_ERROR, KERN_WARNING is enough. 2. In dev_set_promiscuity(), if __dev_set_promiscuity() failed, we return at once. Signed-off-by:

This reverts commit 608961a5. The problem is that the mac80211 stack not only needs to be able to muck with the link-level headers, it also might need to mangle all of the packet data if doing sw wireless encryption. This fixes kernel bugzilla #10903. Thanks to Didier Raboud (for the bugzilla report), Andrew Prince (for bisecting), Johannes Berg (for bringing this bisection analysis to my attention), and Ilpo (for trying to analyze this purely from the TCP side). In 2.6.27 we can take another stab at this, by using something like skb_cow_data() when the TX path of mac80211 ends up with a non-NULL tx->key. The ESP protocol code in the IPSEC stack can be used as a model for implementation. Signed-off-by:
