Hi,
v3:
- Adjust patch 1 and 2 according to Alexander's suggestion.
- Add Tested-by from Subbaraya.
- Add Reviewed-by from Ioana.
v2:
- Inline page_frag_alloc() and {netdev,napi}_alloc_frag()
- Adopt Vlastimil's suggestion and add his Acked-by
In the current implementation of napi_alloc_frag(), it doesn't have any
align guarantee for the returned buffer address. We would have to use
some ugly workarounds to make sure that we can get a align buffer
address for some Ethernet drivers. This patch series tries to introduce
some helper functions to make sure that an align buffer is returned.
Then we can drop the ugly workarounds and avoid the unnecessary memory
waste.

net: octeontx2: Use napi_alloc_frag_align() to avoid the memory waste
