H A Dgeneric_receive_offload_lib.rst40 For different usage scenarios, the GRO library provides two sets of API.
92 The reassembly algorithm determines the efficiency of GRO. There are two
101 The above two challenges require our algorithm is:
107 In DPDK GRO, we use a key-based algorithm to address the two challenges.
117 "neighbor" for it. If find a "neighbor", merge the two packets together.
126 The key-based algorithm has two characters:
144 The table structure used by TCP/IPv4 GRO contains two arrays: flow array
157 Header fields deciding if two packets are neighbors include:
H A Ddmadev.rst51 Each DMA device, whether physical or virtual is uniquely designated by two
102 There are two dequeue APIs ``rte_dma_completed`` and
107 ``status`` array passed by user). These two APIs can also return the last
H A Dip_fragment_reassembly_lib.rst16 For each fragment two new mbufs are created:
57 The basic idea is to use two hash functions and <bucket_entries> \* associativity.
83 #. If no entry with such key is found, then try to create a new one by one of two ways:
H A Dservice_cores.rst28 There are two methods to having service cores in a DPDK application, either by
30 The simpler of the two is to pass the `-s` coremask argument to EAL, which will
H A Dpacket_distrib_lib.rst9 When using this library, the logical cores in use are to be considered in two roles: firstly a dist…
18 There are two modes of operation of the API in the distributor library,
41 This ensures that no two packets with the same tag are processed in parallel,
H A Dring_lib.rst78 It is not possible to create two rings with the same name (rte_ring_create() returns NULL if this i…
93 The ring structure is composed of two head and tail couples; one is used by producers and one is us…
210 This section explains what occurs when two producers concurrently add an object to the ring.
307 The following are two examples that help to explain how indexes are used in a ring.
420 to split public enqueue/dequeue API into two phases:
429 Note that this API is available only for two sync modes:
470 Note that this API is available only for two sync modes:
H A Dlpm_lib.rst46 the lookup operation requires two memory read accesses.
65 By splitting the process in two different tables/levels and limiting the number of tbl8s,
86 The two flags are used to determine whether the entry is valid or not and
101 The two flags show whether the entry and the table are valid respectively.
143 it is found in either one or two memory accesses,
212 since the only difference between the two rules is within the last byte.
H A Dfib_lib.rst80 match rule has a depth larger than 24, the lookup operation will require two
119 By splitting the process into two different tables/levels and limiting the number of tbl8s,
138 These use cases could include storing two next hop IDs inside the 63 bits of the next hop.

52 * A device is provided with two different streams - reception and transmission.
162 Forward packets through two network interfaces:
278 To create two pseudo-Ethernet ports where all traffic sent to a port is looped back

269 The controller has eight pools, with each pool containing two queue pairs, that is, two TX and two …
282 insmod igb max_vfs=2,2 (To enable two Virtual Functions per port)
422 in the command above, it creates two vfs for the first two ixgbe ports.

H A De1000em.rst101 For example, to start a VM with two emulated e1000 devices, issue the following command:
119 This command starts a new virtual machine with two emulated 82540EM devices,
120 backed up with two TAP networking host interfaces, tapvm01 and tapvm02.

44 "block", a "frame" may not span across two "blocks".
H A Dthunderx.rst193 There are two types of VFs:
283 We want to bind two physical interfaces with 24 queues each device, we attach two primary VFs
284 and four secondary VFs. In our example we choose two 10G interfaces eth1 (0002:01:00.2) and eth2 (0…
