bnxt_en: Add support for NAT(L3/L4 rewrite)
Provides support for modifying L3/L4 Header parameters to support NAT.
Sets the appropriate fields/bits in cfa_flow_alloc cmd.
Sample cmd for offloading an IPv4 flow with SNAT:
ovs-ofctl add-flow ovsbr0 "ip,nw_src=192.168.201.44 \
actions=mod_nw_src:203.31.220.144,output:p7p1"
Replace 'nw_src' with 'nw_dst' in above cmd for DNAT with IPv4
Sample cmd for offloading an IPv4 flow with SNAPT:
ovs-ofctl add-flow ovsbr0 "ip,nw_src=192.168.201.44 \
actions=mod_nw_src:203.31.220.144, mod_tp_src:6789,output:p7p1"
Similar to DNAT, replace 'tp_src' with 'tp_dst' for offloading flow
with DNAPT
Sample cmd for offloading an IPv6 flow with SNAT:
ovs-ofctl add-flow ovsbr0 "ipv6, ipv6_src=2001:5c0:9168::2/64 \
actions=load:0x1->NXM_NX_IPV6_SRC[0..63], \
load:0x20010db801920000->NXM_NX_IPV6_SRC[64..127],output:p7p1"
Replace 'SRC' with DST' above for IPv6 DNAT
