| | | | | | | | | | | | | 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.)

* [TCP]: Increase the max_burst threshold from 3 to tp->reordering.John Heffner2008-04-161-2/+5
| | | | | | | | | | | 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: John Heffner <jheffner@napa.(none)> Signed-off-by: David S.

* [NET]: Do not allocate unneeded memory for dev->priv alignment.Pavel Emelyanov2008-04-161-1/+2
| | | | | | | | | | | | | | | | | | | | | 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.
