enum efx_filter_flags

enum efx_filter_flags - flags for hardware filter specifications : Use RSS to spread across multiple queues. By default, matching packets will be delivered only to the specified queue. If this flag is set, they will be delivered to a range of queues offset from the specified queue number according to the indirection table. : Enable DMA scatter on the receiving queue. : Filter is for RX : Filter is for TX

Enumerator:

EFX_FILTER_FLAG_RX_SCATTER
EFX_FILTER_FLAG_RX
EFX_FILTER_FLAG_TX

enum efx_filter_priority

enum efx_filter_priority - priority of a hardware filter specification : Performance hint : Manually configured filter : Required for correct behaviour (user-level networking and SR-IOV)

Enumerator:

EFX_FILTER_PRI_HINT
EFX_FILTER_PRI_MANUAL
EFX_FILTER_PRI_REQUIRED

Definition at line 49 of file filter.h.

enum efx_filter_type

enum efx_filter_type - type of hardware filter : Matching TCP/IPv4 4-tuple : Matching TCP/IPv4 destination (host, port) : Matching UDP/IPv4 4-tuple : Matching UDP/IPv4 destination (host, port) : Matching Ethernet destination MAC address, VID : Matching Ethernet destination MAC address : Matching all otherwise unmatched unicast : Matching all otherwise unmatched multicast : Match type is unspecified

Falcon NICs only support the TCP/IPv4 and UDP/IPv4 filter types.
