A lot of patches are outdated versions of upstreamed patches and drivers. So lets pull in the upstreamed patches and reorder remaining ones. This drops the unnecessary 721-dts-ipq4019-add-ethernet-essedma-node.patch which adds nodes for not yet in OpenWrt IPQESS driver.

Subject: [PATCH 11/11] crypto: qce - handle AES-XTS cases that qce fails
|
|
|
|
QCE hangs when presented with an AES-XTS request whose length is larger
|
|
than QCE_SECTOR_SIZE (512-bytes), and is not a multiple of it. Let the
|
|
fallback cipher handle them.
