net/9p: increase tcp max msize to 1MB
Historically TCP has been limited to 64K buffers, but increasing msize provides huge performance benefits especially as latency increase so allow for bigger buffers. Ideally further improvements could change the allocation from the current contiguous chunk in slab (kmem_cache) to some scatter-gather compatible API... Note this only increases the max possible setting, not the default value. Link: http://lkml.kernel.org/r/YTQB5jCbvhmCWzNd@codewreck.org Signed-off-by: Dominique Martinet <asmadeus@codewreck.org>
