====================
nfp: fix incorrect IPsec checksum handling

this short series resolves two problems with IPsec checksum handling
in the nfp driver.

* PATCH 1/3, 2/3: Correct setting of checksum flags.
  One patch for each of the nfd3 and nfdk datapaths.

* Patch 3/3: Correct configuration of NETIF_F_CSUM_MASK
  so that the stack does not unecessarily calculate csums for
  IPsec offload packets.
