====================
net: ipa: support inline checksum offload

Inline offload--required for checksum offload support on IPA version
4.5 and above--is now supported by the RMNet driver:
  https://lore.kernel.org/netdev/162259440606.2786.10278242816453240434.git-patchwork-notify@kernel.org/

Add support for it in the IPA driver, and revert the commit that
disabled it pending acceptance of the RMNet code.
