2013-05-23bnx2x: Wait for MCP validity during AERYuval Mintz
During PCIe advanced error recovery, the secondary bus reset will cause FW to reset; This will cause the shared memory between it and the driver to be invalidated. During the driver's recovery flow, the driver should not make any assumption on the validity of that memory and instead re-initialize it. This also removes a redundant re-initialization of a previously initialized mutex.

2013-05-23bnx2x: Link-flap avoidance in switch dependent modeDmitry Kravkov
As part of the previous unload flow, probed devices will reset the chip in order to clean the remains of the UNDI driver. As a result, it's possible for the FW to toggle the link. This toggling can prove fatal, as long periods without link can cause the filesystem mount to fail as the storage protocol timeouts. This has been observed against particular switches with long link re-establishment time. This patch informs FW during the reset period that the link should not be toggled - the FW will keep it alive until some interface will load and claim the link as its own.

2013-05-22tg3: Ensure boot code has completed initialization before accessing hardwareNithin Sujir
After resetting the device, the driver waits for a signature to be updated to know that firmware has completed initialization. However, the call to tg3_poll_fw() is being done too late and we're writing to the GRC_MODE register before it has completely initialized, causing contention with firmware. This logic has existed since day one but is causing PCIE link to go down randomly at startup on one platform once every few hundred reboots. Move the tg3_poll_fw() up to before we write to the GRC_MODE register after reset.

Starting with commit 91226790bbe2dbfbba48dd79d49f2b38ef10eb97 `bnx2x: use FW 7.8.17', the bnx2x driver no longer requests the FW to perform IP checksums for IPv4 packets. This behaviour needs to be revised for 57710/57711 chips - when using GSO, if the driver will not set the IP checksum flag then packets will be transmitted by the chip without a valid IP checksum, resulting in a drop of all such packets on the receiver-side.

2013-04-25bnx2x: Prevent NULL pointer dereference in kdumpYuval Mintz
In scenarios in which a previous driver was removed without proper cleanup (e.g., kdump), it is possible for the chip to generate an interrupt without any apparent reason once interrupts are requested. Due to an erroneous initialization of resources, some of the bnx2x structs which are required for interrupt handling are initialized only after an interface's interrupt is requested from the OS. As a result, once such a spurious interrupt occurs, it will cause a NULL pointer dereference - the driver will access those structs in its interrupt handling routine. This patch change the interrupt request scheme so that bnx2x would only request interrupts from the kernel after it has finished initializing all the inner structs required for interrupt handling.

2013-04-24bnx2x: prevent GRO false checksum claimsYuval Mintz
This patch introduces a more robust error handling flow in case of incorrect behaviour by the FW when passing on GRO aggregations. Although this should never happen (i.e., this is merely a theoretical fix), if the bnx2x driver was to receive a GRO from FW with protocol other than IPv4/IPv6, the driver would falsely claim to have performed partial checksum and set various incorrect fields in the skb header. Current behaviour of the bnx2x driver (i.e., print an error) is insufficient. This patch remedies this by simply preventing the false claims.

2013-04-19net: vlan: add protocol argument to packet tagging functionsPatrick McHardy
Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb. The new field fits into a hole (on 64 bit) and doesn't increase the sks's size. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-04-19net: vlan: rename NETIF_F_HW_VLAN_* feature flags to NETIF_F_HW_VLAN_CTAG_*Patrick McHardy
Rename the hardware VLAN acceleration features to include "CTAG" to indicate that they only support CTAGs. Follow up patches will introduce 802.1ad server provider tagging (STAGs) and require the distinction for hardware not supporting acclerating both.

2013-04-18bnx2x: Fix status blocks configurationAriel Elior
This fixes 2 issues regarding bnx2x's status blocks: 1. ethtool -c caused corruption of status blocks in FW RAM. 2. when using multi-CoS, the configuration of the timeout values of status blocks is incorrect, harming the coalescing of interrupts for such CoSs.

2013-04-18bnx2x: Prevent UNDI FW illegal host accessDmitry Kravkov
When loading after UNDI (e.g., Boot from SAN) the UNDI does not gracefully yield its resources; The bnx2x driver handles that release itself. During the manipulation required to release those resources, it's possible for the UNDI to try and write to memory regions which are no longer accessible, causing the PCI bus to prevent further writes from the chip. This would in turn cause DMAE timeouts later on in the driver, as the driver will be unable to use the chip's DMA engines. This patch prevents the chip from actually writing through the PCI bus in said scenario, thus allowing the release without the unfortunate by-product.

2013-04-10bnx2x: Prevent null pointer dereference in AFEX modeYuval Mintz
The cnic module is responsible for initializing various bnx2x structs via callbacks provided by the bnx2x module. One such struct is the queue object for the FCoE queue. If a device is working in AFEX mode and its configuration allows FCoE yet the cnic module is not loaded, it's very likely a null pointer dereference will occur, as the bnx2x will erroneously access the FCoE's queue object. Prevent said access until cnic properly registers itself.

2013-04-09tg3: Use bool not intJoe Perches
Using bool can make code more readable. Convert uses and tests of int to bool. This also makes a comparison of tg3->link_up (itself bool) a bool comparison instead of int. Reorder stack variable declarations to make bool fit declaration holes where appropriate. $ size drivers/net/ethernet/broadcom/tg3.o* text data bss dec hex filename 169958 27249 58896 256103 3e867 drivers/net/ethernet/broadcom/tg3.o.new 169968 27249 58896 256113 3e871 drivers/net/ethernet/broadcom/tg3.o.old Signed-off-by: Joe Perches <joe@perches.com> Reviewed-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.
