* Add optimizing LRO wrapper:Hans Petter Selasky2016-01-192-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Add optimizing LRO wrapper which pre-sorts all incoming packets according to the hash type and flowid. This prevents exhaustion of the LRO entries due to too many connections at the same time. Testing using a larger number of higher bandwidth TCP connections showed that the incoming ACK packet aggregation rate increased from ~1.3:1 to almost 3:1. Another test showed that for a number of TCP connections greater than 16 per hardware receive ring, where 8 TCP connections was the LRO active entry limit, there was a significant improvement in throughput due to being able to fully aggregate more than 8 TCP stream. For very few very high bandwidth TCP streams, the optimizing LRO wrapper will add CPU usage instead of reducing CPU usage. This is expected. Network drivers which want to use the optimizing LRO wrapper needs to call "tcp_lro_queue_mbuf()" instead of "tcp_lro_rx()" and "tcp_lro_flush_all()" instead of "tcp_lro_flush()". Further the LRO control structure must be initialized using "tcp_lro_init_args()" passing a non-zero number into the "lro_mbufs" argument. - Make LRO statistics 64-bit. Previously 32-bit integers were used for statistics which can be prone to wrap-around. Fix this while at it and update all SYSCTL's which expose LRO statistics. - Ensure all data is freed when destroying a LRO control structures, especially leftover LRO entries. - Reduce number of memory allocations needed when setting up a LRO control structure by precomputing the total amount of memory needed. - Add own memory allocation counter for LRO. - Bump the FreeBSD version to force recompilation of all KLDs due to change of the LRO control structure size.

* Update to the Intel ixgbe driver:Jack F Vogel2015-03-1730-8111/+8355
| | | | | | | | | | | | | | | | | | | | | | - Split the driver into independent pf and vf loadables. This is in preparation for SRIOV support which will be following shortly. This also allows us to keep a seperate revision control over the two parts, making for easier sustaining. - Make the TX/RX code a shared/seperated file, in the old code base the ixv code would miss fixes that went into ixgbe, this model will eliminate that problem. - The driver loadables will now match the device names, something that has been requested for some time. - Rather than a modules/ixgbe there is now modules/ix and modules/ixv - It will also be possible to make your static kernel with only one or the other for streamlined installs, or both.

* Start process of removing the use of the deprecated "M_FLOWID" flagHans Petter Selasky2014-12-012-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | from the FreeBSD network code. The flag is still kept around in the "sys/mbuf.h" header file, but does no longer have any users. Instead the "m_pkthdr.rsstype" field in the mbuf structure is now used to decide the meaning of the "m_pkthdr.flowid" field. To modify the "m_pkthdr.rsstype" field please use the existing "M_HASHTYPE_XXX" macros as defined in the "sys/mbuf.h" header file. This patch introduces new behaviour in the transmit direction. Previously network drivers checked if "M_FLOWID" was set in "m_flags" before using the "m_pkthdr.flowid" field. This check has now now been replaced by checking if "M_HASHTYPE_GET(m)" is different from "M_HASHTYPE_NONE". In the future more hashtypes will be added, for example hashtypes for hardware dedicated flows. "M_HASHTYPE_OPAQUE" indicates that the "m_pkthdr.flowid" value is valid and has no particular type. This change removes the need for an "if" statement in TCP transmit code checking for the presence of a valid flowid value. The "if" statement mentioned above is now a direct variable assignment which is then later checked by the respective network drivers like before. Additional notes: - The SCTP code changes will be committed as a separate patch. - Removal of the "M_FLOWID" flag will also be done separately. - The FreeBSD version has been bumped.
