7 contains read-only attributes exposing information about
8 an IPA device. The X values could vary, but are typically
11 What: .../XXXXXXX.ipa/version
14 Contact: Alex Elder <elder@kernel.org>
16 The .../XXXXXXX.ipa/version file contains the IPA hardware
17 version, as a period-separated set of two or three integers
18 (e.g., "3.5.1" or "4.2").
20 What: .../XXXXXXX.ipa/feature/
23 Contact: Alex Elder <elder@kernel.org>

29 What: .../XXXXXXX.ipa/feature/rx_offload
32 Contact: Alex Elder <elder@kernel.org>
34 The .../XXXXXXX.ipa/feature/rx_offload file contains a
35 string indicating the type of receive checksum offload
36 that is supported by the hardware. The possible values
37 are "MAPv4" or "MAPv5".
39 What: .../XXXXXXX.ipa/feature/tx_offload
42 Contact: Alex Elder <elder@kernel.org>
44 The .../XXXXXXX.ipa/feature/tx_offload file contains a
45 string indicating the type of transmit checksum offload
46 that is supported by the hardware. The possible values
47 are "MAPv4" or "MAPv5".
49 What: .../XXXXXXX.ipa/modem/
52 Contact: Alex Elder <elder@kernel.org>
54 The .../XXXXXXX.ipa/modem/ directory contains a set of
55 attributes describing properties of the modem execution
56 environment reachable by the IPA hardware.
58 What: .../XXXXXXX.ipa/modem/rx_endpoint_id
61 Contact: Alex Elder <elder@kernel.org>
63 The .../XXXXXXX.ipa/feature/rx_endpoint_id file contains
64 the AP endpoint ID that receives packets originating from
65 the modem execution environment. The "rx" is from the
66 perspective of the AP; this endpoint is considered an "IPA
67 producer". An endpoint ID is a small unsigned integer.
69 What: .../XXXXXXX.ipa/modem/tx_endpoint_id
72 Contact: Alex Elder <elder@kernel.org>
74 The .../XXXXXXX.ipa/feature/tx_endpoint_id file contains
75 the AP endpoint ID used to transmit packets destined for
76 the modem execution environment. The "tx" is from the
77 perspective of the AP; this endpoint is considered an "IPA
78 consumer". An endpoint ID is a small unsigned integer.
