Compilation fails without mlx5 installed.

I had to remove the default = ["mlx5"] line from core/cargo.toml. It seems --no-default-feature does not work because core is a dependency.

Running this command takes forever:

Hello Team,

I'm planning to use retina as URL filter and block selected URL's. Is there any example like DPDK-l2fw as I need to add retina as transparent bridge. Please advice.

Hi,

I was trying to filter out the TCP packets involved in a 3-way handshake scenario. Are there any pre-built filters that I can utilize to capture the SYN, SYN-ACK and ACK packets?

admin@AN450:~/retina$ sudo env LD_LIBRARY_PATH=$LD_LIBRARY_PATH RUST_LOG=error ./target/release/client_randoms -c configs/online.toml
Initializing Retina runtime...

I am running Retina in online mode using an Intel X710. I found that during setup I would get the following error:

Ethdev port_id=0 invalid rss_hf: 0x3afbc, valid value: 0x7ef8

This is associated with how Retina configures DPDK RSS:

Changing to port_conf.rx_adv_conf.rss_conf.rss_hf = 0x7ef8; resolves the problem for X710's.

Given the error was able to provide a valid config, I'm expecting there is a way to check the supported types before assignment and configure the field based on what the NIC supports.

0x7ef8 = RTE_ETH_RSS_FRAG_IPV4 | RTE_ETH_RSS_NONFRAG_IPV4_TCP | RTE_ETH_RSS_NONFRAG_IPV4_UDP | RTE_ETH_RSS_NONFRAG_IPV4_SCTP | RTE_ETH_RSS_NONFRAG_IPV4_OTHER | RTE_ETH_RSS_FRAG_IPV6 | RTE_ETH_RSS_NONFRAG_IPV6_TCP | RTE_ETH_RSS_NONFRAG_IPV6_UDP | RTE_ETH_RSS_NONFRAG_IPV6_SCTP | RTE_ETH_RSS_NONFRAG_IPV6_OTHER | RTE_ETH_RSS_L2_PAYLOAD
