2012-02-223com/typhoon: reuse eth_mac_addr()Danny Kukawka1-13/+1
Use eth_mac_addr() for .ndo_set_mac_address, remove typhoon_set_mac_address() since it do currently the same as eth_mac_addr(). Additional advantage: eth_mac_addr() already checks if the given address is valid. Signed-off-by: Danny Kukawka <[email protected]> Acked-by: Dave Dillow <[email protected]> Signed-off-by: David S.

The patch provides workaround for BUG in FW 7.2.16, which in GRO mode may miscalculate buffer and place on SGE one frag less than it could. It may happen only for some MTUs, we mark these MTUs with gro_check flag during device initialization or MTU change. Next FW should include fix for the issue and the patch could be reverted.

2012-02-20use FW 7.2.16Dmitry Kravkov8-82/+177
The patch integrates FW 7.2.16 HSI and implements driver part of GRO flow. FW 7.2.16 adds the ability to aggregate packets for GRO (and not just LRO) and also fixes some bugs. 1. Added new aggregation mode: GRO. In this mode packets are aggregated such that the original packets can be reconstructed by the OS. 2. 57712 HW bug workaround - initialized all CAM TM registers to 0x32. 3. Adding the FCoE statistics structures to the BNX2X HSI. 4. Wrong configuration of TX HW input buffer size may cause theoretical performance effect. Performed configuration fix. 5. FCOE - Arrival of packets beyond task IO size can lead to crash. Fix firmware data-in flow. 6. iSCSI - In rare cases of on-chip termination the graceful termination timer hangs, and the termination doesn't complete. Firmware fix to MSL timer tolerance. 7. iSCSI - Chip hangs when target sends FIN out-of-order or with isles open at the initiator side. Firmware implementation corrected to drop FIN received out-of-order or with isles still open. 8. iSCSI - Chip hangs when in case of retransmission not aligned to 4-bytes from the beginning of iSCSI PDU. Firmware implementation corrected to support arbitrary aligned retransmissions. 9. iSCSI - Arrival of target-initiated NOP-IN during intense ISCSI traffic might lead to crash.

2012-02-19atl1c: dont use highprio tx queueEric Dumazet1-4/+0
This driver attempts to use two TX rings but lacks proper support : 1) IRQ handler only takes care of TX completion on first TX ring 2) the stop/start logic uses the legacy functions (for non multiqueue drivers) This means all packets witk skb mark set to 1 are sent through high queue but are never cleaned and queue eventualy fills and block the device, triggering the infamous "NETDEV WATCHDOG" message. Lets use a single TX ring to fix the problem, this driver is not a real multiqueue one yet. Minimal fix for stable kernels.

2012-02-16sfc: Add SR-IOV back-end support for SFC9000 familyBen Hutchings13-26/+2192
On the SFC9000 family, each port has 1024 Virtual Interfaces (VIs), each with an RX queue, a TX queue, an event queue and a mailbox register. These may be assigned to up to 127 SR-IOV virtual functions per port, with up to 64 VIs per VF. We allocate an extra channel (IRQ and event queue only) to receive requests from VF drivers. There is a per-port limit of 4 concurrent RX queue flushes, and queue flushes may be initiated by the MC in response to a Function Level Reset (FLR) of a VF. Therefore, when SR-IOV is in use, we submit all flush requests via the MC. The RSS indirection table is shared with VFs, so the number of RX queues used in the PF is limited to the number of VIs per VF. This is almost entirely the work of Steve Hodgson, formerly [email protected]. Signed-off-by: Ben Hutchings <[email protected]>
2012-02-16sfc: Allocate SRAM between buffer table and descriptor caches at init timeBen Hutchings6-14/+50

2012-02-16sfc: Disable flow control during flushesSteve Hodgson3-0/+9
The TX DMA engine issues upstream read requests when there is room in the TX FIFO for the completion. However, the fetches for the rest of the packet might be delayed by any back pressure. Since a flush must wait for an EOP, the entire flush may be delayed by back pressure. Mitigate this by disabling flow control before the flushes are started. Since PF and VF flushes run in parallel introduce fc_disable, a reference count of the number of flushes outstanding. The same principle could be applied to Falcon, but that would bring with it its own testing. Signed-off-by: Ben Hutchings <[email protected]>

2012-02-16sfc: Leave interrupts and event queues enabled whenever we canBen Hutchings4-318/+308
When SR-IOV is enabled we may receive FLR (Function-Level Reset) events, associated queue flush events and requests from VF drivers at any time. Therefore we need to keep event queues and interrupts enabled whenever possible. Currently we stop interrupt-driven event processing before flushing RX and TX queues; efx_nic_flush_queues() then polls event queues for flush events and discards any others it finds. Change it to work with the regular event handling functions. Currently efx_start_channel() fills RX queues synchronously when a device is brought up. This could now race with NAPI, so change it to send fill events. This was almost entirely written by Steve Hodgson, formerly [email protected]. Signed-off-by: Ben Hutchings <[email protected]>

The RMFT_DEST_MAC and TMFT_SRC_MAC register fields were previously documented as 44 bits wide, whereas a MAC address has 48 bits. Thankfully the hardware uses the correct width and the driver has used separate definitions that divide each of these into 32-bit and 16-bit fields. Fix the initial definitions for these fields and rewrite the latter definitions to use them. Signed-off-by: Ben Hutchings <[email protected]>
