From e9da2a14ec116912033a88f08261bc193a9c445d Mon Sep 17 00:00:00 2001 From: Xavier Simonart Date: Sat, 14 Apr 2018 17:19:41 +0200 Subject: Add support for reception of jumbo frames Jumbo frames are now supported through the addition of a "mtu" parameter of the port in the config file. Setting the mtu to a value higher than 1500 bytes will enable the reception of jumbo frames. In addition, the rte_eth_dev_set_mtu is now set for all pmds. Finally, setting mbuf_size does not set MEMPOOL_F_NO_SPREAD anymore. This option was only used for pure debugging. Big packets can be received using two ways - Using multiple "small" mbufs, i.e. around 2K. This is the default. - Using one big mbuf holding the whole packet. This can be enabled by setting a parameter mbuf_size in the receiving core configuration Change-Id: Idd60ad31f41c89f9522dff4d894af2696b7a2ea1 Signed-off-by: Xavier Simonart --- VNFs/DPPD-PROX/prox_port_cfg.c | 10 ++++------ 1 file changed, 4 insertions(+), 6 deletions(-) (limited to 'VNFs/DPPD-PROX/prox_port_cfg.c') diff --git a/VNFs/DPPD-PROX/prox_port_cfg.c b/VNFs/DPPD-PROX/prox_port_cfg.c index c4787b1e..c00948ad 100644 --- a/VNFs/DPPD-PROX/prox_port_cfg.c +++ b/VNFs/DPPD-PROX/prox_port_cfg.c @@ -294,12 +294,10 @@ static void init_port(struct prox_port_cfg *port_cfg) port_cfg->socket, port_cfg->n_rxd); dummy_pool_name[0]++; } else { - // Most pmd do not support setting mtu yet... - if (!strcmp(port_cfg->short_name, "ixgbe")) { - plog_info("\t\tSetting MTU size to %u for port %u ...\n", port_cfg->mtu, port_id); - ret = rte_eth_dev_set_mtu(port_id, port_cfg->mtu); - PROX_PANIC(ret < 0, "\n\t\t\trte_eth_dev_set_mtu() failed on port %u: error %d\n", port_id, ret); - } + // Most pmd should now support setting mtu + plog_info("\t\tSetting MTU size to %u for port %u ...\n", port_cfg->mtu, port_id); + ret = rte_eth_dev_set_mtu(port_id, port_cfg->mtu); + PROX_PANIC(ret < 0, "\n\t\t\trte_eth_dev_set_mtu() failed on port %u: error %d\n", port_id, ret); if (port_cfg->n_txq == 0) { /* not sending on this port */ -- cgit 1.2.3-korg
