[dpdk-dev] [PATCH] net/vmxnet3: remove IP checksum from Tx/Rx offload capa

The vmxnet3_prep_pkts function set rte_errno to ENOTSUP for any packets
having PKT_TX_IP_CHECKSUM set in ol_flags. But the vmxnet3 has
DEV_TX_OFFLOAD_IPV4_CKSUM set in this tx offload capa.
This issue has been introduced with the new Rx offload
API. DEV_TX_OFFLOAD_IPV4_CKSUM and DEV_RX_OFFLOAD_IPV4_CKSUM has been
added to the tx/rx offloads capa, but the vmxnet3 driver doesn't support
it.
To fix the issue, DEV_TX/RX_OFFLOAD_IPV4_CKSUM needs to be removed from
tx/rx offload capa.
Fixes: 95e4a96ccbf1 ("net/vmxnet3: convert to new Rx offload API")
