2009-11-04tcp: Do not call IPv4 specific func in tcp_check_reqGilad Ben-Yossef1-6/+3
Calling IPv4 specific inet_csk_route_req in tcp_check_req is a bad idea and crashes machine on IPv6 connections, as reported by Valdis Kletnieks Also, all we are really interested in is the timestamp option in the header, so calling tcp_parse_options() with the "estab" set to false flag is an overkill as it tries to parse half a dozen other TCP options.

2009-11-02gianfar: Add Multiple group SupportSandeep Gopalpet4-209/+422
This patch introduces multiple group support for etsec2.0 devices. Multiple group support is provided by mapping the set of enabled queues to different groups and then programming the per group regsiters imask, ievent, rstat, tstat. The queues corresponding to a group are indicated by programming isrg (interrupt steering) registers. Signed-off-by: Sandeep Gopalpet <Sandeep.Kumar@freescale.com> Signed-off-by: David S.

2009-11-02gianfar: Add Multiple Queue SupportSandeep Gopalpet4-290/+621
This patch introduces multiple Tx and Rx queues. The incoming packets can be classified into different queues based on filer rules (out of scope of this patch). The number of queues enabled will be based on a DTS entries fsl,num_tx_queues and fsl,num_rx_queues. Although we are enabling multiple queues, the interrupt coalescing is on per device level (etsec-1.7 doesn't support multiple rxics and txics).

2009-11-02gianfar: Introduce logical group support.Sandeep Gopalpet4-200/+250
This patch introduces the group structure. The elements of this structure are the interrupt lines, their corresponding names, the register memory map. The elements for this group are factored out from the gfar_private structure. The introduction of group structure will help in providing support for newer versions of etsec. Currently, the support is present only for single group and single tx/rx queues. Signed-off-by: Sandeep Gopalpet <Sandeep.Kumar@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-11-02gianfar: Add per queue structure supportSandeep Gopalpet4-245/+398
This patch introduces per tx and per rx queue structures. Earlier the members of these structures were inside the gfar_private structure. Moving forward if we want to support multiple queues, we need to refactor the gfar_private structure so that introduction of multiple queues is easier.

2009-11-02tg3 / broadcom: Add code to disable rxc refclkMatt Carlson3-2/+46
The 5785 does not use the RXC reference clock. Turning it off is desirable as it saves power. By default, the 50610 enables the RXC reference clock and the 50610M disables it. Presumably this is one of the reasons why the hardware architect chose one over the other. Adding a "rx reference clock disable" flag is not the ideal way to describe the option, as it would force the MAC using a 50610M to set the flag. Ideally we want the flags to represent opt-in behavior that deviates from hardware defaults. Furthermore, the lack of a "disable" flag implies that the requester wants the rx reference clock enabled, which doesn't necessarily follow. By presenting the option as a passive statement (rx reference clock unused) rather than a command, I hope to convey an opt-in option to disable the rx reference clock that falls back to hardware defaults if not set. A secondary benefit of this is that it keeps the intelligence about phy defaults in the broadcom module where it belongs and allows the broadcom module more latitude should a bug arise.

2009-11-02tg3 / broadcom: Refine AC131 APD supportMatt Carlson2-3/+6
Auto power-down (APD) support is a power-saving feature. It should be selectively enabled since it might expose MAC bugs. This patch changes the code to enable APD only if the PHY_BRCM_AUTO_PWRDWN_ENABLE flag is set. The tg3 driver was changed to set this bit.

2009-11-02tg3 / broadcom: Add PHY_BRCM_CLEAR_RGMII_MODE flagMatt Carlson3-0/+8
Broadcom 50610M parts changed the default definitions of the RGMII mode shadow register. The 5785 needs the RGMII mode selection bits [4:3] cleared. The default value of the remaining bits in this register are zero. Rather than unnecessarily burn an extra bit in the dev_flags member in an attempt to enumerate all possible combinations, this patch take a more course grained approach and labels the option as "clear all bits".
