Hi Manuel,
Did you use DPDK with the OpenSSL crypto backend?
Could you provide traces of the packets on the encrypting node?
Regards,
Sergio

Hello Sergio,
>From my side, your patch looks good to me.
Nevertheless I can't manage to properly run encryption/decryption (ipsec
between two boards) with the Octeon CPT hardware. (Same ipsec scenario setup
via openssl is actually working as expected)
Do not know whether the problem is because of these qp issues or different
problems (dpdk-test-crypto-perf tool to test dpdk devices is working as
expected).
Board decrypting is dropping packets because of errors in llc-input :
sh errors: 58359552 llc-input unknown llc
ssap/dsap
Typically, tracing packets, I see:
Packet 1
00:01:00:408970: dpdk-input
VirtualFunctionEthernet1/0/1 rx queue 0
buffer 0x10c2b: current data 0, length 102, buffer-pool 0, clone-count 0,
totlen-nifb 0, trace 0x0
ext-hdr-valid
l4-cksum-computed l4-cksum-correct
PKT MBUF: port 0, nb_segs 1, pkt_len 102
buf_len 2176, data_len 102, ol_flags 0x180, data_off 128, phys_addr
0x20861680
packet_type 0x0 l2_len 0 l3_len 0 outer_l2_len 0 outer_l3_len 0
rss 0x0 fdir.hi 0x0 fdir.lo 0x0
Packet Offload Flags
PKT_RX_IP_CKSUM_GOOD (0x0080) IP cksum of RX pkt. is valid
PKT_RX_L4_CKSUM_GOOD (0x0100) L4 cksum of RX pkt. is valid
0x0000: 02:0f:b7:00:00:00 -> 02:0f:b7:00:00:01
00:01:00:408981: ethernet-input
frame: flags 0x3, hw-if-index 1, sw-if-index 1
0x0000: 02:0f:b7:00:00:00 -> 02:0f:b7:00:00:01
00:01:00:408985: llc-input
LLC 0x18 -> null, control 0x1000
00:01:00:408989: error-drop
llc-input: unknown llc ssap/dsap
Any idea about this llc-input issue? (It looks to be unrelated the qp problem
but I do not have background enough to assert that)
BR,
Manuel
