2011-09-16ath6kl: refactor firmware ext data addr and reserved ram handling sizeKalle Valo
Less if clauses this way and again easier to override the values. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-09-16ath6kl: refactor firmware load address codeKalle Valo
Currently the load address was calculated everytime when it was needed, and with a mess if clauses. Simplify this by adding a field to struct ath6kl for each address and choose the address with simple switch statements. Also move the code just after target version is retrieved. That way it's easier to override the values later in the boot process. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2011-09-16ath6kl: fix busy loop in ath6kl_bmi_get_rx_lkahd()Kalle Valo
Brent reported that ath6kl busy loops if firmware doesn't boot for some reason (in this case he was using an older firmware which wasn't supported by ath6kl). Investigation revealed that this was even on purpose, ath6kl_bmi_get_rx_lkahd() had a parameter to disable the timeout check, which is extremely evil. I didn't find any reason why the timeout needs to be disabled so I just removed the feature. The function already busyloops a maximum of one second if it doesn't get an answer, even that's too long. If something takes longer than that a more friendly approach is needed. Reported-by: Brent Taylor <btaylor1@motorolasolutions.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2011-09-16ath6kl: query device tree for firmware board-idSam Leffler
When no default board data file is present query the device tree for a board-id setting to identify the board data to use.

2011-09-15ixgbe: Correctly name and handle MSI-X other interruptAlexander Duyck
It was possible to inadvertently add additional interrupt causes to the MSI-X other interrupt. This occurred when things such as RX buffer overrun events were being triggered at the same time as an event such as a Flow Director table reinit request. In order to avoid this we should be explicitly programming only the interrupts that we want enabled. In addition I am renaming the ixgbe_msix_lsc function and interrupt to drop any implied meaning of this being a link status only interrupt. Unfortunately the patch is a bit ugly due to the fact that ixgbe_irq_enable needed to be moved up before ixgbe_msix_other in order to have things defined in the correct order.

2011-09-15ixgbe: cleanup configuration of EITRSEL and VF reset pathAlexander Duyck
This change is meant to cleanup some of the code related to SR-IOV and the interrupt registers. Specifically I am moving the EITRSEL configuration into the MSI-X configuration section instead of enablement. Also I am fixing the VF shutdown path since it had operations in the incorrect order.

2011-09-15ixgbe: cleanup reset pathsAlexander Duyck
The reset paths are overly complicated and are either missing steps or contain extra unnecessary steps such as reading MAC address twice.

2011-09-15ixgbe: Update TXDCTL configuration to correctly handle WTHRESHAlexander Duyck

2011-09-15ixgbe: combine PCI_VDEVICE and board declaration to same lineAlexander Duyck
This patch is a minor whitespace cleanup to compress the device ID declaration and board type declaration onto the same line. It seems to make sense since all of the combinations of the two are less than 80 characters and it makes the overall layout a bit more readable.

2011-09-15v2 ixgbe: consolidate all MSI-X ring interrupts and poll routines into oneAlexander Duyck
This change consolidates all of the MSI-X interrupt and polling routines into two single functions. One for the interrupt and one for the code. The main advantage to doing this is that the compiler can optimize the routines into single monolithic functions which should allow all of them function to occupy a single block of memory and as such avoid jumping around.

2011-09-15ixgbe: Change default Tx work limit size to 256 buffersAlexander Duyck
This change makes it so that the default Tx work limit is 256 buffers or 1/2 of an entire ring instead of a full ring size so that it is much more likely that we will be able to actually reach the work limit value. Previously with the value set to an entire ring it would not have been possible for us to trigger an event due to the fact that the Tx work is stopped at the point where we cannot place one more buffer on the ring and it is not restarted until cleanup is complete.

2011-09-15net: consolidate and fix ethtool_ops->get_settings callingJiri Pirko
This patch does several things: - introduces __ethtool_get_settings which is called from ethtool code and from drivers as well. Put ASSERT_RTNL there. - dev_ethtool_get_settings() is replaced by __ethtool_get_settings() - changes calling in drivers so rtnl locking is respected. In iboe_get_rate was previously ->get_settings() called unlocked. This fixes it. Also prb_calc_retire_blk_tmo() in af_packet.c had the same problem. Also fixed by calling __dev_get_by_index() instead of dev_get_by_index() and holding rtnl_lock for both calls. - introduces rtnl_lock in bnx2fc_vport_create() and fcoe_vport_create() so bnx2fc_if_create() and fcoe_if_create() are called locked as they are from other places. - use __ethtool_get_settings() in bonding code Signed-off-by: Jiri Pirko <jpirko@redhat.com> v2->v3: -removed dev_ethtool_get_settings() -added ASSERT_RTNL into __ethtool_get_settings() -prb_calc_retire_blk_tmo - use __dev_get_by_index() and lock around it and __ethtool_get_settings() call v1->v2: add missing export_symbol Reviewed-by: Ben Hutchings <bhutchings@solarflare.com> [except FCoE bits] Acked-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.
