2011-01-17ath9k_hw: do PA offset calibration only on longcal intervalRajkumar Manoharan1-5/+5
The power detector adc offset calibration has to be done on 4 minutes interval (longcal * pa_skip_count). But the commit "ath9k_hw: fix a noise floor calibration related race condition" makes the PA calibration executed more frequently beased on nfcal_pending value. Running PAOffset calibration lesser than longcal interval doesn't help anything and the worse part is that it causes NF load timeouts and RX deaf conditions. In a very noisy environment, where the distance b/w AP & station is ~10 meter and running a downlink udp traffic with frequent background scan causes "Timeout while waiting for nf to load: AR_PHY_AGC_CONTROL=0x40d1a" and moves the chip into deaf state. This issue was originaly reported in Android platform where the network-manager application does bgscan more frequently on AR9271 chips. (AR9285 family usb device).

There is an interoperability with AR9382/AR9380 in L1 state with a few root complexes which can cause a hang. This is fixed by setting some work around bits on the PCIE PHY.

pcmcia_request_irq() and pcmcia_enable_device() are intended to be called from process context (first function allocate memory with GFP_KERNEL, second take a mutex). We can not take spin lock and call them. It's safe to move spin lock after pcmcia_enable_device() as we still hold off IRQ until dev->base_addr is 0 and driver will not proceed with interrupts when is not ready.

2011-01-10ipw2200: Check for -1 INTA in tasklet too.Indan Zupancic1-0/+7
This is an attempt to fix a long standing open bug: http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1334 The interrupt handler checks for INTA being -1, apparently that means that the hardware is gone. But the interrupt handler defers actual interrupt processing to a tasklet. By the time the tasklet is run and checks INTA again, the hardware might be gone and INTA be -1, which confuses the driver because all event bits are set. The patch applies to 2.6.37.

Specifically I updated the masks to work correctly with the latest version of ethtool, I cleaned up the exception handling and added detailed error output when a filter is rejected, and corrected several bits that were set incorrectly in ixgbe_type.h.

2011-01-09ixgbe: further flow director performance optimizationsAlexander Duyck4-44/+194
This change adds a compressed input type for atr signature hash computation. It also drops the use of the set functions when setting up the ATR input since we can then directly setup the hash input as two dwords that can be stored and passed as registers. With these changes the cost of computing the has is low enough that we can perform a hash computation on each TCP SYN flagged packet allowing us to drop the number of flow director misses considerably in tests such as netperf TCP_CRR.

This patch powers down (only when WoL is disabled) the PHY after a reset if the interface is down and the ethtool diagnostics are not currently running. The ethtool diagnostic function required a minor re-factor as a result, and the e1000_[get|put]_hw_control() functions are renamed since they are no longer static to netdev.c as they are needed by the ethtool diagnostics.

2011-01-09net/fec: add dual fec support for mx28Shawn Guo3-21/+139
This patch is to add mx28 dual fec support. Here are some key notes for mx28 fec controller. - The mx28 fec controller naming ENET-MAC is a different IP from FEC used on other i.mx variants. But they are basically compatible on software interface, so it's possible to share the same driver. - ENET-MAC design on mx28 made an improper assumption that it runs on a big-endian system. As the result, driver has to swap every frame going to and coming from the controller. - The external phys can only be configured by fec0, which means fec1 can not work independently and both phys need to be configured by mii_bus attached on fec0. - ENET-MAC reset will get mac address registers reset too. - ENET-MAC MII/RMII mode and 10M/100M speed are configured differently FEC. - ETHER_EN bit must be set to get ENET-MAC interrupt work.
