The main purpose of this patchset is to add AF_XDP support for UMEM
chunk sizes > PAGE_SIZE. This is enabled for UMEMs backed by HugeTLB
pages.
Changes since v2:
* Related fixes/improvements included with v2 have been removed. These
changes have all been resubmitted as standalone patchsets.
* Minimize uses of #ifdef CONFIG_HUGETLB_PAGE.
* Improve AF_XDP documentation.
* Update benchmark table in commit message.
Changes since v1:
* Add many fixes/improvements to the XSK selftests.
* Add check for unaligned descriptors that overrun UMEM.
* Fix compile errors when CONFIG_HUGETLB_PAGE is not set.
* Fix incorrect use of _Static_assert.
* Update AF_XDP documentation.
* Rename unaligned 9K frame size test.
* Make xp_check_dma_contiguity less conservative.
* Add more information to benchmark table.
Thanks to Magnus Karlsson for all his support!
Happy easter!
