2006-01-17[PATCH] e1000: Fix Desc. Rings and Jumbo FramesJeff Kirsher
This patch contains two fixes. The first fix is to the tx and rx descriptor rings clean up process. The second fix is to jumbo frames, which cleans up the code logic and removes most of the fifo related limitations on jumbo frames. This is because the driver code now supports splitting a packet across multiple descriptors.

2006-01-17[PATCH] mv643xx_eth: Receive buffers require 8 byte alignmentDale Farnsworth

Buffers allocated by dev_alloc_skb() only have 4-byte alignment when slab debugging is enabled. Also, document that the 2-byte offset to align the IP packets on receive is a hardware feature and is not tied to NET_IP_ALIGN.

2006-01-17[IPV4]: rt_cache_stat can be statically definedEric Dumazet
Using __get_cpu_var(obj) is slightly faster than per_cpu_ptr(obj, raw_smp_processor_id()). 1) Smaller code and memory use For static and small objects, DEFINE_PER_CPU(type, object) is preferred over a alloc_percpu() : Better and smaller code to access them, and no extra memory (storing the pointer, and the percpu array of pointers) x86_64 code before patch mov 1237577(%rip),%rax # ffffffff803e5990 <rt_cache_stat> not %rax # part of per_cpu machinery mov %gs:0x3c,%edx # get cpu number movslq %edx,%rdx # extend 32 bits cpu number to 64 bits mov (%rax,%rdx,8),%rax # get the pointer for this cpu incl 0x38(%rax) x86_64 code after patch mov $per_cpu__rt_cache_stat,%rdx mov %gs:0x48,%rax # get percpu data offset incl 0x38(%rax,%rdx,1) 2) False sharing avoidance for SMP : For a small NR_CPUS, the array of per cpu pointers allocated in alloc_percpu() can be <= 32 bytes. This let slab code gives a part of a cache line. If the other part of this 64 bytes (or 128 bytes) cache line is used by a mostly written object, we can have false sharing and expensive per_cpu_ptr() operations. Size of rt_cache_stat is 64 bytes, so this patch is not a danger of a too big increase of bss (in UP mode) or static per_cpu data for SMP (PERCPU_ENOUGH_ROOM is currently 32768 bytes) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.
