2013-04-10sky2: Threshold for Pause Packet is set wrongMirko Lindner
[ Upstream commit 74f9f42c1c1650e74fb464f76644c9041f996851 ] The sky2 driver sets the Rx Upper Threshold for Pause Packet generation to a wrong value which leads to only 2kB of RAM remaining space. This can lead to Rx overflow errors even with activated flow-control. Fix: We should increase the value to 8192/8 Signed-off-by: Mirko Lindner <mlindner@marvell.com> Acked-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S.

2013-04-10sky2: Receive Overflows not countedMirko Lindner
[ Upstream commit 9cfe8b156c21cf340b3a10ecb3022fbbc1c39185 ] The sky2 driver doesn't count the Receive Overflows because the MAC interrupt for this event is not set in the MAC's interrupt mask. The MAC's interrupt mask is set only for Transmit FIFO Underruns. Fix: The correct setting should be (GM_IS_TX_FF_UR | GM_IS_RX_FF_OR) Otherwise the Receive Overflow event will not generate any interrupt. The Receive Overflow interrupt is handled correctly Signed-off-by: Mirko Lindner <mlindner@marvell.com> Acked-by: Stephen Hemminger <stephen@networkplumber.org> Signed-off-by: David S.

2012-10-30skge: Add DMA mask quirk for Marvell 88E8001 on ASUS P5NSLI motherboardGraham Gower
[ Upstream commit a2af139ff1cd85df586690ff626619ab1ee88b0a ] Marvell 88E8001 on an ASUS P5NSLI motherboard is unable to send/receive packets on a system with >4gb ram unless a 32bit DMA mask is used. This issue has been around for years and a fix was sent 3.5 years ago, but there was some debate as to whether it should instead be fixed as a PCI quirk. http://www.spinics.net/lists/netdev/msg88670.html However, 18 months later a similar workaround was introduced for another chipset exhibiting the same problem. http://www.spinics.net/lists/netdev/msg142287.html Signed-off-by: Graham Gower <graham.gower@gmail.com> Signed-off-by: Jan Ceuleers <jan.ceuleers@computer.org> Acked-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2012-07-12sky2: fix checksum bit management on some chipsstephen hemminger
[ Upstream commit 5ff0feac88ced864f44adb145142269196fa79d9 ] The newer flavors of Yukon II use a different method for receive checksum offload. This is indicated in the driver by the SKY2_HW_NEW_LE flag. On these newer chips, the BMU_ENA_RX_CHKSUM should not be set. The driver would get incorrectly toggle the bit, enabling the old checksum logic on these chips and cause a BUG_ON() assertion. If receive checksum was toggled via ethtool.

2012-05-20sky2: fix receive length error in mixed non-VLAN/VLAN trafficstephen hemminger
[ Upstream commit e072b3fad5f3915102c94628b4971f52ff99dd05 ] Bug: The VLAN bit of the MAC RX Status Word is unreliable in several older supported chips. Sometimes the VLAN bit is not set for valid VLAN packets and also sometimes the VLAN bit is set for non-VLAN packets that came after a VLAN packet. This results in a receive length error when VLAN hardware tagging is enabled. Fix: Variation on original fix proposed by Mirko. The VLAN information is decoded in the status loop, and can be applied to the received SKB there. This eliminates the need for the separate tag field in the interface data structure. The tag has to be copied and cleared if packet is copied. This version checked out with vlan and normal traffic. Note: vlan_tx_tag_present should be renamed vlan_tag_present, but that is outside scope of this.

2012-05-20sky2: propogate rx hash when packet is copiedstephen hemminger
[ Upstream commit 3f42941b5d1d13542b1a755a9e4f633aa72e4d3e ] When a small packet is received, the driver copies it to a new skb to allow reusing the full size Rx buffer. The copy was propogating the checksum offload but not the receive hash information. The bug is impact was mostly harmless and therefore not observed until reviewing this area of code.

2011-11-17sky2: enforce minimum ring sizestephen hemminger
The hardware has a restriction that the minimum ring size possible is 128.

2011-09-27skge: handle irq better on single port cardStephen Hemminger
Most boards with SysKonnect/Marvell Ethernet have only a single port. For the single port case, use the standard Ethernet driver convention of allocating IRQ when device is brought up rather than at probe time. This patch also adds some additional read after writes to avoid any PCI posting problems when setting the IRQ mask. The error handling of dual port cards is also changed. If second port can not be brought up, then just fail. No point in continuing, since the failure is most certainly because of out of memory. It is worth noting that the dual port skge device has a single irq but two seperate status rings and therefore has two NAPI objects, one for each port.
