From HW point of view it is possible to use all filters for a single interface. Currently ethtool doesn't support modifying filter count so that user can allocate more filters to a interface and less to others. This patch adds ETHTOOL_SRXCLSRLCNT ioctl command for modifying filter count. example command: ./ethtool -U eth0 rule-count 256 Signed-off-by: Sunil Goutham --- include/uapi/linux/ethtool.h | 1 + net/ethtool/ioctl.c | 1 + 2 files changed, 2 insertions(+) diff --git a/include/uapi/linux/ethtool.h b/include/uapi/linux/ethtool.h index 67aa713..178f346 100644 --- a/include/uapi/linux/ethtool.h +++ b/include/uapi/linux/ethtool.h @@ -1552,6 +1552,7 @@ enum ethtool_fec_config_bits { #define ETHTOOL_PHY_STUNABLE 0x0000004f /* Set PHY tunable configuration */ #define ETHTOOL_GFECPARAM 0x00000050 /* Get FEC settings */ #define ETHTOOL_SFECPARAM 0x00000051 /* Set FEC settings */ +#define ETHTOOL_SRXCLSRLCNT 0x00000052 /* Set RX class rule count */ /* compatibility with older code */ #define SPARC_ETH_GSET ETHTOOL_GSET diff --git a/net/ethtool/ioctl.c b/net/ethtool/ioctl.c index 6134b18..ca0f75e 100644 --- a/net/ethtool/ioctl.c +++ b/net/ethtool/ioctl.c @@ -2863,6 +2863,7 @@ int dev_ethtool(struct net *net, struct ifreq *ifr) case ETHTOOL_SRXFH: case ETHTOOL_SRXCLSRLDEL: case ETHTOOL_SRXCLSRLINS: + case ETHTOOL_SRXCLSRLCNT: rc = ethtool_set_rxnfc(dev, ethcmd, useraddr); break; case ETHTOOL_FLASHDEV:
