2014-04-22wil6210: relaxed check for BACK start sequenceVladimir Kondratiev
Sometimes, due to the race between Rx path and WMI_BA_STATUS_EVENTID WMI event, few frames may be passed to the stack before reorder buffer allocated. Then, after BACK establishment, it start getting frames with sequence number ahead of SSN, and it get interpreted as missing frames. Then, BACK mechanism will wait for missing frames; data traffic will be stopped. In case of interface configured for DHCP, this data delay causes DHCP failure. Relax checking for sequence number; use sequence of 1-st frame handled by the buffer as SSN for this buffer. This is work-around, real fix should be done when proper BACK mechanism implemented.

2014-04-22rtl8180: be paranoid in stopping unused queues.Andrea Merello
HW should never attempt to perform DMA for unused queues. For rtl8187se this is ensured by setting a dedicated register at init time, before enabling TX. In rtl8180/5 the register is only written at the first TX (because in rtl8180/5 it serves also to kick DMA for used queues). This should be enough, but it's worth to add a register write at init time, before enabling TX. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: John W.

2014-04-22rtl8180: add parentheses to REG_ADDR macrosAndrea Merello

2014-04-22rtl8180: fix enabled interrupt mask for rtl8187seAndrea Merello
When preparing the bitfield to write to HW register, the high-priority queue error interrupt bit is set two times, and the beacon queue TX-OK interrupt is not enabled. Currently this have no functional impact because the high-priority queue is not used at all, and the beacon queue is not used yet. This patch removes high-priority queue bits and it adds the beacon queue missing bit. It removes also the management queue bits because it is not used. This was found by static code analyzer.

2014-04-16net: mvneta: properly configure the MAC <-> PHY connection in all situationsThomas Petazzoni
Commit 5445eaf309ff ('mvneta: Try to fix mvneta when compiled as module') fixed the mvneta driver to make it work properly when loaded as a module in SGMII configuration, which was tested successful by the author on the Armada XP OpenBlocks AX3, which uses SGMII. However, some other platforms, namely the Armada XP GP don't use SGMII, but a QSGMII connection between the MAC and the PHY, and this case was not supported by the mvneta driver, which was relying on configuration put in place by the bootloader. While this works when the mvneta driver is built-in (because clocks are not gated), it breaks when mvneta is built as a module, because the clock is gated (all configuration is lost) and then re-enabled when the mvneta driver is loaded. In order to support all of RGMII, SGMII and QSGMII, this commit reworks how the PHY interface configuration is done, and simplifies it: it removes the mvneta_port_sgmii_config() and mvneta_gmac_rgmii_set() functions, which were strange because mvneta_gmac_rgmii_set() was called in all cases, even for SGMII configurations. Also, the mvneta_gmac_rgmii_set() function was taking a boolean as argument, which was always true. Instead, all the PHY interface configuration logic is moved into the mvneta_port_power_up() function, in a much simpler 'switch' construct, with four cases: - QSGMII: the RGMIIEn bit, the PCSEn bit in GMAC_CTRL_2 are set, and the SERDES is configured in QSGMII. Technically speaking, configuring the SERDES of the first port would be sufficient, but it is simpler to do it on all ports. - SGMII: the RGMIIEn bit, the PCSEn bit in GMAC_CTRL_2 are set, and the SERDES is configured as SGMII. - RGMII: the RGMIIEn bit in GMAC_CTRL_2 is set. The PCSEn bit is kept cleared, and no SERDES configuration is done, because RGMII is not using SERDES lanes. - other: an error is returned. For this reason, the mvneta_port_power_up() now returns an int instead of nothing, and the return value is checked by mvneta_probe(). This has been successfully tested on: * Armada XP DB, which has two RGMII and two SGMII connections * Armada XP GP, which uses QSGMII for its four interfaces * Armada 370 Mirabox, which has two RGMII connections Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: David S.

2014-04-16sfc:On MCDI timeout, issue an FLR (and mark MCDI to fail-fast)Edward Cree
When an MCDI command times out (whether or not we find it completed when we poll), call efx_mcdi_abandon(), which tells all subsequent MCDI calls to fail-fast, and queues up an FLR. Because an FLR doesn't lead to receiving any reboot even from the MC (unlike most other types of reset), we have to call efx_ef10_reset_mc_allocations. In efx_start_all(), if a reset (of any kind) is pending, we bail out. Without this, attempts to reconfigure (e.g. change mtu) can cause driver/mc state inconsistency if the first MCDI call triggers an FLR. For similar reasons, on EF10, in efx_reset_down(method=RESET_TYPE_MCDI_TIMEOUT), set the number of active queues to zero before calling efx_stop_all(). And, on farch, in efx_reset_up(method=RESET_TYPE_MCDI_TIMEOUT), set active_queues and flushes pending & outstanding to zero. efx_mcdi_mode_{poll,event}() should not take us out of fail-fast mode. Instead, this is done by efx_mcdi_reset() after the FLR completes. The new FLR reset_type RESET_TYPE_MCDI_TIMEOUT doesn't really fit into the hierarchy of reset 'scopes' whereby efx_reset() decides some resets subsume others. Thus, it uses separate logic. Also, fixed up some inconsistency around RESET_TYPE_MC_BIST, which was in the wrong place in that hierarchy. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S.
