2006-05-20[PATCH] skge: don't allow transmit ring to be too smallStephen Hemminger
The driver will get stuck (permanent transmit timeout), if the transmit ring size is set too small. It needs to have enough ring elements to hold one maximum size transmit. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-05-20[PATCH] skge: bad checksums on big-endian platformsStephen Hemminger
Skge driver always causes bad checksums on big-endian. The checksum in the receive control block was being swapped when it doesn't need to be. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-05-20[PATCH] Subjec: sky2, skge: correct PCI id for DGE-560TStephen Hemminger
The Dlink DGE-560T uses Yukon2 chipset so it needs sky2 driver; and the DGE-530T uses Yukon1 so it uses skge driver. Bug: http://bugzilla.kernel.org/show_bug.cgi?id=6544 Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-04-12[PATCH] dlink pci cards using wrong driverStephen Hemminger
This patch fixes the problem of some Dlink cards picking the wrong driver. It looks like these cards use Yukon 1 chipset, not Yukon 2. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-03-23[PATCH] skge: compute available ring buffersStephen Hemminger
Don't need to keep track of available buffers, it is simpler to just compute the value (ala e1000). Don't need tes on link up because should always have available buffers then. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-23[PATCH] skge: dont free skb until multi-part transmit completeStephen Hemminger
Don't free transmit buffers until the whole set of transmit descriptors has been marked as done. Otherwise, we risk freeing a skb before the whole transmit is done. This changes the transmit completion handling from incremental to a two pass algorithm. First pass scans and records the start of the last done descriptor, second cleans up until that point.

2006-03-23[PATCH] skge: rx_reuse called twiceStephen Hemminger
In the error case we call skge_rx_reuse twice. This is harmless but unnecessary. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-23[PATCH] skge: dont use dev_alloc_skb for rx buffsStephen Hemminger
The skge driver was using dev_alloc_skb which reserves space for the Ethernet header. This unnecessary and it should just use alloc_skb, also by using GFP_KERNEL during startup it won't run into problems when a user asks for a huge ring size or mtu and potentially drains the reserved atomic pool. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-23[PATCH] skge: align receive buffersStephen Hemminger
The skge driver aligns the header on the initial receive buffers, but but doesn't on followon receive buffer allocations. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-03-21[PATCH] skge: dma configuration cleanupStephen Hemminger
Cleanup of the part of the code that sets up DMA configuration. Should cause no real change in operation, just clearer. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] skge: check the allocation of ring bufferStephen Hemminger
The SysKonnect Genesis and Yukon chip sets have restrictions on the possible control block area. The memory needs to not cross 4 Gig boundary, and it needs to be 8 byte aligned. This patch checks and fails to bring the device up if region is unacceptable. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] skge: use auto masking of irqsStephen Hemminger
Improve performance of skge driver by not touching irq mask register as much. Since the interrupt source auto-masks, the driver can just leave it disabled until the end of the soft irq. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-03-21[PATCH] skge: use NAPI for tx cleanup.Stephen Hemminger
Cleanup transmit buffers using NAPI. This allows the transmit routine to leave interrupts enabled, and that improves performance. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2006-02-23skge: protect interrupt maskStephen Hemminger
There is a race between updating the irq mask and setting it which can be triggered on SMP with a bad cable. Similar patch from Ingo Molnar and Thomas Gleixner Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
2006-02-23skge: genesis phy initialzationStephen Hemminger
The SysKonnect Genesis based board would fail on initialization with phy_read errors caused by not waiting for last phy write. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
2006-02-23skge: NAPI/irq race fixStephen Hemminger
Fix a race in the receive NAPI, irq handling. The interrupt clear and the start need to be separated. Otherwise there is a window between the last frame received and the NAPI done level handling. Signed-off-by: Stephen Hemminger <shemminger@osdl.org>
2006-02-17[PATCH] skge: speed settingStephen Hemminger
This is a clone of John Linville's fixed for speed setting on sky2 driver. The skge driver has the same code (and bug). It would not allow manually forcing 100 and 10 mbit. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
2006-01-17[PATCH] skge: fix dma mask setup.Stephen Hemminger
There are a couple of problems in the DMA setup code for skge. * In the 64 bit case, it doesn't set the consistent mask. * In the 32 bit case, the error check is backwards! It likely will only be visible as a bug on 64 bit platforms. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2005-12-24[PATCH] skge: handle out of memory on MTU size changesStephen Hemminger
Changing the MTU size causes the receiver to have to reallocate buffers. If this allocation fails, then we need to return an error, and take the device offline. It can then be brought back up or reconfigured for a smaller MTU. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2005-12-01[PATCH] skge: handle VLAN checksum correctly on yukon rev 0Stephen Hemminger
If using UDP over VLAN, with the skge driver there is a possibility of generating an incorrect checksum. This is a unlikely occurrence because it is only an issue on Yukon revision 0, and that revision doesn't seem to exist on any current hardware (probably early prototype).
