Hello,
> The pci-epf-test driver recently moved to the pci_epc_mem_map() API.
> This API call handle unaligned addresses seamlessly, if the EPC driver
> being used has implemented the .align_addr callback.
>
> This means that pci-epf-test no longer need any special padding to the
> buffers that is allocated on the host side. (This was only done in order
> to satisfy the EPC's alignment requirements.)
>
> In fact, to test that the pci_epc_mem_map() API is working as intended,
> it is important that the host side does not only provide buffers that
> are nicely aligned.

> However, since not all EPC drivers have implemented the .align_addr
> callback, add support for capabilities in pci-epf-test, and if the
> EPC driver implements the .align_addr callback, set a new
> CAP_UNALIGNED_ACCESS capability. If CAP_UNALIGNED_ACCESS is set, do not
> allocate overly sized buffers on the host side.

Applied to endpoint, thank you!
