Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/

IF_ADDR_UNLOCK() across network device drivers when accessing the per-interface multicast address list, if_multiaddrs. This will allow us to change the locking strategy without affecting our driver programming interface or binary interface. For two wireless drivers, remove unnecessary locking, since they don't actually access the multicast address list. Approved by: re (kib) MFC after: 6 weeks

Separate multicast filtering of SysKonnect GENESIS and Marvell

2009-05-01T03:24:03Z

Yukon from common multicast handling code. Yukon uses hash-based multicast filtering(big endian form) but GENESIS uses perfect multicast filtering as well as hash-based one(little endian form). Due to the differences of multicast filtering there is no much sense to have a common code. o Remove sk_setmulti() and introduce sk_rxfilter_yukon(), sk_rxfilter_yukon() that handles multicast filtering setup. o Have sk_rxfilter_{yukon, genesis} handle promiscuous mode and nuke sk_setpromisc(). This simplifies ioctl handler as well as giving a chance to check validity of Rx control register of Yukon. o Don't reinitialize controller when IFF_ALLMULTI flags is changed. o Nuke sk_gmchash(), it's not needed anymore. o Always reconfigure Rx control register whenever a new multicast filtering condition is changed. This fixes multicast filtering setup on Yukon. PR: kern/134051

Prefer NULL over integer 0 for pointer type.

allocator for jumbo frame. o Removed unneeded jlist lock which was used to manage jumbo buffers. o Don't reinitialize hardware if MTU was not changed. o Added additional check for minimal MTU size. o Added a new tunable hw.skc.jumbo_disable to disable jumbo frame support for the driver. The tunable could be set for systems that do not need to use jumbo frames and it would save (9K * number of Rx descriptors) bytes kernel memory. o Jumbo buffer allocation failure is no longer critical error for the operation of sk(4). If sk(4) encounter the allocation failure it just disables jumbo frame support and continues to work without user intervention. With these changes jumbo frame performance of sk(4) was slightly increased and users should not encounter jumbo buffer allocation failure. Previously sk(4) tried to allocate physically contiguous memory, 3388KB for 256 Rx descriptors. Sometimes that amount of contiguous memory region could not be available for running systems which in turn resulted in failure of loading the driver.

Give MEXTADD() another argument to make both void pointers to the

free function controlable, instead of passing the KVA of the buffer storage as the first argument. Fix all conventional users of the API to pass the KVA of the buffer as the first argument, to make this a no-op commit. Likely break the only non-convetional user of the API, after informing the relevant committer. Update the mbuf(9) manual page, which was already out of sync on this point. Bump __FreeBSD_version to 800016 as there is no way to tell how many arguments a CPP macro needs any other way. This paves the way for giving sendfile(9) a way to wait for the passed storage to have been accessed before returning. This does not affect the memory layout or size of mbufs. Parental oversight by: sam and rwatson. No MFC is anticipated.
