Some systems do not like 82571/2 use of 16-bit MSI messages and some other systems claim to support MSI, but neither really works. Setup a test MSI handler to detect whether or not MSI is working properly, and if not, fallback to legacy INTx interrupts. Signed-off-by:

The e1000e driver was based on a version of e1000 prior to acme's introduction of skb_copy_to_linear_data_offset, and was submitted after acme went through and coverted all the drivers to use it. Signed-off-by:

Two regressions were introduced by the recent tlan: 64bit conversion commit (93e16847). The first in TLan_GetSKB caused a NULL pointer dereference. With the second causing the link to fail to come up. Signed-off-by:

On my test box with the Asus M3A32-MVP main board there is a regression from 2.6.26 related to suspend, hibernation and shutdown. Namely, if Wake-on-LAN is enabled with 'ethtool -s eth0 wol g', the box hangs solid during all of these operations, while executing either sky2_suspend(), or sky2_shutdown(). This patch fixes it for me. Signed-off-by:

gfar_halt() was factored out into halting and disabling by commit d87eb127, as the suspend() method only wants to do the former. However, the call to gfar_halt_nodisable() from gfar_halt() apparently got lost during the patch respin process. This adds it back. Signed-off-by:

This patch makes the multicast socket to be per namespace. When a network namespace is created, other than the init_net and a multicast packet is received, the kernel goes to a hang or a kernel panic. How to reproduce ? * create a child network namespace * create a pair virtual device veth * ip link add type veth * move one side to the pair network device to the child namespace * ip link set netns <childpid> dev veth1 * ping -I veth0 224.0.0.1 The bug appears because the function ip_mc_init_dev does not initialize the different multicast fields as it exits because it is not the init_net. BUG: soft lockup - CPU#0 stuck for 61s!

Minor code improvements Small changes to make the code a little bit more efficient and mostly more readable: - Using unified macros for EMAC_RD/WR which looks like normal REG_RD/WR - Removing the NIG_WR since it did nothing and was only confusing - On bnx2x_panic_dump, print only the used parts of the rings - define parameters only on the branch they are needed and not at the beginning of the function - using NETIF_MSG_INTR and not private BNX2X_MSG_SP for debug prints Signed-off-by:

8073 PHY changes The initial support we had for this PHY needs some serious changing.

Pause settings - 1G pause was not working due to missing write to the emac block (TX_MODE_FLOW_EN) - The flow control should use the negotiated result (after autoneg) so we should save both the requested autoneg and the result - The HW credits with flow control at 1G speed were not optimized and caused low throughput - It is recommended to turn off flow control if the MTU is bigger than 5000B due to internal buffers size Signed-off-by:

Yaniv Rosner authored
Link order with external PHY When external PHY exists (second chip with the PHY to translate to another physical medium) the link with the eternal PHY and the network should be established before setting the link between the 5771x and the PHY. This is the right order and it is important when using autoneg - the link to the network should use the autoneg and the link between the two chips should be forced to the network result.

Load/Unload under traffic Few issues were found when loading and unloading under traffic: - When receiving Tx interrupt call netif_wake_queue if the queue is stopped but the state is open - Check that interrupts are enabled before doing anything else on the msix_fp_int function - In nic_load, enable the interrupts only when needed and ready for it - Function stop_leading returns status since it can fail - Add 1ms delay when unloading the driver to validate that there are no open transactions that already started by the FW - Splitting the "has work" function into Tx and Rx so the same function will be used on unload and interrupts - Do not request for WoL if only resetting the device (save the time that it takes the FW to set the link after reset) - Fixing the device reset after iSCSI boot and before driver load - all internal buffers must be cleared before the driver is loaded Signed-off-by:

FW Internal Memory structure The FW uses data structures on the chip internal memory to aggregate the connections when TPA is enabled.

Statistics - Making sure that each drop is accounted for in the driver statistics - Clearing the FW statistics when driver is loaded to prevent inconsistency with HW statistics - Once error is detected (bnx2x_panic_dump), stop the statistics before other actions (currently it is stopped last and can corrupt the data) - Adding HW checksum error counter to the statistics - Removing unused variable stats_ticks - Using macros instead of magic numbers to indicate which statistics are shared per port and which are per function Signed-off-by:
