2008-02-26[MACVLAN]: Update Kconfig to refer to iproutePatrick McHardy
Since the macvlan release I had at least 5 users asking how to configure it since the old userspace tool doesn't work with the version in the kernel. Add a pointer to the Kconfig help. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-02-26RDMA/nes: Fix interrupt moderation low thresholdJohn Lacombe
Interrupt moderation low threshold value was incorrectly triggering, indicating that the threshold should be lowered. The impact was the timer was likely to become 40usecs and get stuck there. The biggest side effect was too many interrupts and nonoptimal performance.

2008-02-26RDMA/nes: Fix CRC endianness for RDMA connection establishment on big-endianFaisal Latif
With commit ef19454b ("[LIB] crc32c: Keep intermediate crc state in cpu order"), the behavior of crc32c changes on big-endian platforms. Our algorithm expects the previous behavior; otherwise we have RDMA connection establishment failure on big-endian platforms like powerpc. Apply cpu_to_le32() to value returned by crc32c() to get the previous behavior.

This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place.

2008-02-26maple: fix device detectionAdrian McMenamin
The maple bus driver that went into the kernel mainline in September 2007 contained some bugs which were revealed by the update of the kobj code for the current release series. Unfortunately those bugs also helped ensure maple devices were properly detected. This patch (against the current git) now ensures that devices are properly detected again. (A previous attempt to fix this by delaying initialisation only partially fixed this - as became apparent when the bus was fully loaded) Signed-off-by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Adrian Bunk pointed out that a Coverity scan found some apparently dead code in nes_verbs.c that really shouldn't have been dead. The function nes_create_cq() was missing the assignment err = 1; just prior to an iteration that conditionally set err = 0 if a PBL was found for a given virtual CQ.

A single entry (addr 0x10001000, size 0x2000) will get converted to page address 0x10000000 with a page size of 0x4000. The code as it stands doesn't address the single buffer case, but in fact it allows the subsequent single-buffer special case to be eliminated entirely. Because the mask now includes the (page adjusted) starting and ending addresses, the general case works for the single buffer case as well.

This behavior has been confirmed by Marvell with a SATA analyzer. The Marvell port-multiplier apparently likes to see clean HOB information when accessing PMP registers. Since sata_mv uses PIO shadow register access, this doesn't happen automatically, as it might in a more purely FIS-based driver (eg. ahci). One way to fix this is to flag these commands with ATA_TFLAG_LBA48, forcing libata to write out the HOB fields with known (zero) values.

2008-02-24libata: automatically use DMADIR if drive/bridge requires itTejun Heo
Back in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir. That's nice, but most SATA devices which need it will tell us about it in their IDENTIFY PACKET response, as bit-15 of word-62 of the returned data (as per ATA7, ATA8 specifications). So for those which specify it, we should automatically use the DMADIR bit. Otherwise, disc writing will fail by default on many SATA-ATAPI drives. This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it if atapi_dmadir is set or identify data indicates DMADIR is necessary. atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting DMADIR.

This counter is valuable to determine if the system is unable to timely return buffers to the hardware and this counter starts to increase well before the hardware starts to drop packets. If users experience rx_no_buffer_count increasing, they should increase the amount of descriptors. That will provide more buffers for the hardware and will decrease the chance of hard drops.
