MFC r275358 r275483 r276982 - Removing M_FLOWID by hps@

r275358: Start process of removing the use of the deprecated "M_FLOWID" flag 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 This check has now now been replaced by checking if "M_HASHTYPE_GET(m)" is different from "M_HASHTYPE_NONE".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. r275483: Remove M_FLOWID from SCTP code. r276982: Remove no longer used "M_FLOWID" flag from mbuf.h and update the netisr manpage. Note: The FreeBSD version has been bumped. Reviewed by: hps, tuexen Sponsored by: Limelight Networks

cxgb: replace r273280 with a more comprehensive fix. Poll for link state when the link is down, even for interrupt capable PHYs. Allow PHYs to report a dubious "partial" link. If this state is seen 3 consecutive times (each check is ~1s apart) then reset the PHY. This is a workaround for a situation where repeatedly toggling the link from the peer gets the AEL2005 PHY into a state where it never establishes a PCS block lock even when everything is in order.

Update OFED to Linux 3.7 and update Mellanox drivers.

2013-09-29T00:35:03Z

Update the OFED Infiniband core to the version supplied in Linux version 3.7. The update to OFED is nearly all additional defines and functions with the exception of the addition of additional parameters to ib_register_device() and the reg_user_mr callback. In addition the ibcore (Infiniband core) and ipoib (IP over Infiniband) have both been made into completely loadable modules to facilitate testing of the OFED stack in FreeBSD. Finally the Mellanox Infiniband drivers are now updated to the latest version shipping with Linux 3.7.
