Use netdev_alloc_skb since it handles any NUMA node memory localtion issues and sets skb->dev. Since device driver was not setting skb->dev, I bet filter rules based on device would not work. Signed-off-by:

Any negative return value from start_xmit is interpreted as NETDEV_TX_LOCK which is not what this driver wants. It should return 0 (NETDEV_TX_OK) when it consumes a packet. Also, use skb_padto() as the generic way to pad small frames. Signed-off-by:

This patch works around the MWI bug on the DC21143 rev 65 Tulip by ensuring that the receive buffers don't end on a cache line boundary (as documented in the errata). This patch is required for the MIPS based Cobalt Qube/RaQ as supporting the extra PCI commands seems to reduce the chance of a hard lockup between the Tulip and the PCI bridge. Signed-off-by:

winbond-840 shares tulip.h with the tulip driver, because they share many (but not all) of the same register definitions. This is useful for the register definitions, but not helpful when it comes to symbols that are shared among the tulip driver's C modules, but not meant to be shared outside that one driver. Thus, PKT_BUF_SZ is a symbol internal to tulip, but it was intruding upon a similar symbol in winbond-840's namespace. This was not a problem as long as the two symbols had the same value, but upcoming patches result in differing symbol values. Signed-off-by: -

Having the id field be an int was making more complex bus topologies excessively difficult. For now, just convert it to a string, and change all instances of "bus->id = val" to snprintf(id, MII_BUS_ID_LEN, "%x", val). Signed-off-by:

Poll the completed TX frames in gfar_poll(). This prevents the tx completion interrupt from interfering with processing of received frames. We also disable hardware rx coalescing when NAPI is enabled. Signed-off-by:

This patch revises the logging for link informations of spidernet. - The link down message is too verbose because auto-negotiation timeout occurs periodically while an ethernet cable is not connected. - We want to see the link result, and we think it should be displayed.

In addition to the value of GHIINT0STS, spidernet interrupt handler should check the values of GHIINT1STS/GHIINT2STS registers at the beginning of spider_net_interrupt() so as not to drop error interrupts. GHIINT1STS/GHIINT2STS registers indicates some of erroneous conditions in spidernet, and a few bits of GHIINT0STS register reflects these conditions. But GHIINT0MSK masks these bits, so you should check these conditions by reading GHIINT1STS/GHIINT2STS registers directly. Signed-off-by:

Pass a struct mv643xx_private * to the register accessor functions, as a preparation for having multiple mv643xx_eth silicon blocks. (Since this causes some 80 column straddling, and the mv_ prefix is useless anyway, rename mv_read to rdl and mv_write to wrl to compensate.) Signed-off-by:

- Remove unused MV643XX_DEFAULT_[RT]X_QUEUE_SIZE definitions. - Remove ETH_TARGET enum -- it isn't used anywhere in the driver, and isn't even valid for non-mv643xx chip models, as those use different MBUS target IDs. - Clean up comment and control flow in mv643xx_eth_change_mtu(). - Use mp->dev instead of mp->mii.dev in mv643xx_eth_tx_timeout_task(). - Make mv643xx_eth_free_tx_descs() static. - Remove overzealous NULL check in mv643xx_eth_start_xmit(). - Use symbolic NETDEV_TX_* constants in mv643xx_eth_start_xmit().

This change is necessary to allow cwnd to grow during persistent reordering. Cwnd moderation is applied when in the disorder state and an ack that fills the hole comes in. If the hole was greater than 3 packets, but less than tp->reordering, cwnd will shrink when it should not have. Signed-off-by:

The alloc_netdev_mq() tries to produce 32-bytes alignment for both the net_device itself and its private data. The second alignment is achieved by adding the NETDEV_ALIGN_CONST to the whole size of the memory to be allocated. However, for those devices that do not need the private area, this addition just makes the net_device weight 1024 + 32 = 1068 bytes, i.e. consume twice as much memory. Since loopback device is such (sizeof_priv == 0 for it), and each net namespace creates one, this can save a noticeable amount of memory for kernel with net namespaces turned on. After this set the lo device is actually allocated from a size-1024 kmem cache on i386 box even with NETPOLL and WIRELESS_EXT turned on. Signed-off-by:
