2008-09-05mv643xx_eth: smi sharing is a per-unit property, not a per-port oneLennert Buytenhek
Which top-level unit's SMI interface to use should be a property of the top-level unit, not of the individual ports. This patch moves the ->shared_smi pointer from the per-port platform data to the global platform data. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-09-05mv643xx_eth: require contiguous receive and transmit queue numberingLennert Buytenhek
Simplify receive and transmit queue handling by requiring the set of queue numbers to be contiguous starting from zero. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-09-05mv643xx_eth: get rid of compile-time configurable transmit checksummingLennert Buytenhek
Get rid of the mv643xx_eth-internal MV643XX_ETH_CHECKSUM_OFFLOAD_TX compile-time option. Using transmit checksumming is the sane default, and anyone wanting to disable it should use ethtool(8) instead of recompiling their kernels. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-09-05mv643xx_eth: get rid of receive-side lockingLennert Buytenhek
By having the receive out-of-memory handling timer schedule the napi poll handler and then doing oom processing from the napi poll handler, all code that touches receive state moves to napi context, letting us get rid of all explicit locking in the receive paths since the only mutual exclusion we need anymore at that point is protection against reentering ourselves, which is provided by napi synchronisation. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-09-05mv643xx_eth: make napi unconditionalLennert Buytenhek
Make napi unconditional on the receive side, so that we can get rid of all the locking and local interrupt disabling in the receive path. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-09-05mv643xx_eth: use the SMI done interrupt to wait for SMI access completionLennert Buytenhek
If the platform code has passed us the IRQ number of the mv643xx_eth top-level error interrupt, use the error interrupt to wait for SMI access completion instead of polling the SMI busy bit, since SMI bus accesses can take up to tens of milliseconds. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-09-05mv643xx_eth: switch ->phy_lock from a spinlock to a mutexLennert Buytenhek
Since commit 81600eea98789da09a32de69ca9d3be8b9503c54 ("mv643xx_eth: use auto phy polling for configuring (R)(G)MII interface"), mv643xx_eth no longer does SMI accesses from interrupt context. The only other callers that do SMI accesses all do them from process context, which means we can switch the PHY lock from a spinlock to a mutex, and get rid of the extra locking in some ethtool methods. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-09-05mv643xx_eth: get rid of modulo operationsLennert Buytenhek
Get rid of the modulo operations that are currently used for computing successive TX/RX descriptor ring indexes. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-09-05mv643xx_eth: get rid of IRQF_SAMPLE_RANDOMLennert Buytenhek
Using IRQF_SAMPLE_RANDOM for the mv643xx_eth interrupt handler significantly increases interrupt processing overhead, so get rid of it. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>
2008-09-05mv643xx_eth: fix receive buffer DMA unmappingLennert Buytenhek
When tearing down a DMA mapping for a receive buffer, we should pass dma_unmap_single() the exact same address that dma_map_single() gave us when we originally set up the mapping. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com>

2008-08-27e1000: fix stack sizeLinus Torvalds
Here's the patch. It shrinks the stack from 1152 bytes to 192 bytes (the first version, that only did the e1000_option part, got it down to 600 bytes). About half comes from not using multiple "e1000_option" structures, the other half comes from turning the "e1000_opt_list[]" arrays into "static const" instead, so that gcc doesn't copy them onto the stack.

2008-08-27forcedeth: fix checksum flagAyaz Abdulla
Fix the checksum feature advertised in device flags. The hardware support TCP/UDP over IPv4 and TCP/UDP over IPv6 (without IPv6 extension headers). However, the kernel feature flags do not distinguish IPv6 with/without extension headers. Therefore, the driver needs to use NETIF_F_IP_CSUM instead of NETIF_F_HW_CSUM since the latter includes all IPv6 packets. A future patch can be created to check for extension headers and perform software checksum calculation.

2008-08-27ibmveth: fix bad UDP checksumsSantiago Leon
This patch fixes a ibmveth bug where bad UDP checksums are being transmitted when checksum offloading is enabled. The hypervisor does checksum offloading only on TCP packets, so ibmveth calls skb_checksum_help() for any other protocol. The bug happens because the packet is being modified after the DMA map, so we would need a memory barrier before making the hypervisor call. Reordering the code so that the DMA map happens after skb_checksum_help() has the additional advantage of fixing a DMA map leak if skb_checksum_help() where to fail.
