New header\nfile of 'rte_eth_features.h' is added.\n* 'is_command_supported': It is for capability discovery,\n that is to check if specific feature/command is\n supported on a port.\n* 'rx_classification_filter_ctl': It is for receive\n classification filter configuring. e.g. selecting hash\n function, possibly configuring flow director. It is a\n common API where a lot of commands can be implemented\n for different sub features, to avoid defining quite a\n lot of ops for device specific features.\n* 'rte_eth_features.h': It includes all the feature\n commands which can be checked and processed in above\n two ops. Also it may include other commands for future\n implementations.\n\nSigned-off-by: Helin Zhang <helin.zhang@intel.com>\n---\n lib/librte_ether/Makefile | 1 +\n lib/librte_ether/rte_eth_features.h | 73 +++++++++++++++++++++++++++++++++++++\n lib/librte_ether/rte_ethdev.c | 31 ++++++++++++++++\n lib/librte_ether/rte_ethdev.h | 55 ++++++++++++++++++++++++++++\n 4 files changed, 160 insertions(+)\n create mode 100644 lib/librte_ether/rte_eth_features.h", "diff": "diff --git a/lib/librte_ether/Makefile b/lib/librte_ether/Makefile\nindex b310f8b..8089723 100644\n--- a/lib/librte_ether/Makefile\n+++ b/lib/librte_ether/Makefile\n@@ -46,6 +46,7 @@ SRCS-y += rte_ethdev.c\n #\n SYMLINK-y-include += rte_ether.h\n SYMLINK-y-include += rte_ethdev.h\n+SYMLINK-y-include += rte_eth_features.h\n \n # this lib depends upon:\n DEPDIRS-y += lib/librte_eal lib/librte_mempool lib/librte_ring lib/librte_mbuf\ndiff --git a/lib/librte_ether/rte_eth_features.h b/lib/librte_ether/rte_eth_features.h\nnew file mode 100644\nindex 0000000..983d7c6\n--- /dev/null\n+++ b/lib/librte_ether/rte_eth_features.h\n@@ -0,0 +1,73 @@\n+/*-\n+ * BSD LICENSE\n+ *\n+ * Copyright(c) 2010-2014 Intel Corporation.
