* ixgbe: Do not attempt to perform interrupts in netpoll when downAlexander Duyck2010-01-141-0/+4
| | | | | | | | | | | | This patch resolves issues seen when running netconsole and rebooting via reboot -f. The issue was due to the fact that we were attempting to perform interrupt actions when the q_vectors and rings had already been freed via the ixgbe_shutdown routines.

| * iwlwifi: silence buffer overflow warningDan Carpenter2010-01-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Smatch (and presumably other static checkers) complain that MAX_TID_COUNT is past the end of the array. In the resulting discussion, Zhu Yi pointed out that this value is not used in real life and the assignment was only there to silence a gcc warning. If there were a bug in the surrounding code and the value were used, the WARN_ON(!qc) would print a warning before the crash.

| * iwlwifi: disable tx on beacon update notificationAbhijeet Kolekar2010-01-081-20/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On beacon change update notification from mac we are not disabling the tx in adhoc mode. Mac sends BSS_CHANGED_BEACON_ENABLED when station leaves IBSS. Driver should indicate uCode to not to send anything on receiving this notification. Functionality to indicate uCode is duplicated across two notifications so created a common function called iwl_set_no_assoc. Fix the issue at http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2133.

| * iwlwifi: fix iwl_queue_used bug when read_ptr == write_ptrZhu Yi2010-01-081-1/+1

Because there is no used TFD in this case. This is a complementary fix to the fix already included in commit "iwl3945: fix panic in iwl3945 driver". Both fixes are needed to address the panic below.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current rt2x00 drivers may result in a "ieee80211_tx_status: headroom too small" error message when a frame needs to be properly aligned before transmitting it. This is because the space needed to ensure proper alignment isn't requested from mac80211. Fix this by adding sufficient amount of alignment space to the amount of headroom requested for TX frames.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 8bf3d79bc401ca417ccf9fc076d3295d1a71dbf5 enabled EEPROM checksum checks to avoid bogus bug reports but failed to address updating the code to consider devices with custom EEPROM sizes. Devices with custom sized EEPROMs have the upper limit size stuffed in the EEPROM. Use this as the upper limit instead of the static default size. In case of a checksum error also provide back the max size and whether or not this was the default size or a custom one. If the EEPROM is busted we add a failsafe check to ensure we don't loop forever or try to read bogus areas of hardware.

| | | | | | | | | | | | | | | | | | | | | | | | Due to a change in pci_restore_state()[1] which clears the saved_state flag, the driver should call pci_save_state() to set the flag once again to avoid issues with EEH (same fix that recently was submitted for ixgbe).

| | | | | | | | | | | | | | | | | | | | | | | | In the driver probe function the emac module clock needs to be enabled before calling register_netdev(). As soon as the device is registered the driver get_stats function can be invoked by the core - the module clock must be switched on to be able to read from stats registers.

There is no difference in the PCI device ids for the two different configurations, so these drivers both claim the device ids. However, it is possible to distinguish the two configurations by the presence of Open Firmware properties for them, so we do that.

* | mv643xx_eth: don't include cache padding in rx desc buffer sizeSaeed Bishara2010-01-071-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If NET_SKB_PAD is not a multiple of the cache line size, mv643xx_eth allocates a couple of extra bytes at the start of each receive buffer to make the data payload end up on a cache line boundary. These extra bytes are skb_reserve()'d before DMA mapping, so they should not be included in the DMA map byte count (as the mapping is done starting at skb->data), nor should they be included in the receive descriptor buffer size field, or the hardware can end up DMAing beyond the end of the buffer, which can happen if someone sends us a larger-than-MTU sized packet. This problem was introduced in commit 7fd96ce47ff ("mv643xx_eth: rework receive skb cache alignment", May 6 2009), but hasn't appeared to be problematic so far, probably as the main users of mv643xx_eth all have NET_SKB_PAD == L1_CACHE_BYTES.
