The dot11ExcludeUnencrypted MIB is set to true.Ĭonfirm that each MPDU has a distinct Packet Number that is larger than prior PNs.A cipher key is available to decrypt the packet and a privacy exemption is defined for the packet's Ethertype that specifies a WDI_EXEMPT_ON_ KEY_UNAVAILABLE action.If the frame is unencrypted, discard if:.A privacy exemption is defined for the packet's ether type that specifies an WDI_EXEMPT_ ALWAYS action.The packet fails the replay mechanism defined for the cipher algorithm (see Rx PN/replay check).The packet payload fails the MIC verification.
If it does not match any of the receive packet filters.Determine when to release pending frames even if their preceding frames have not arrived.ĭetermine which Rx frames need to be discarded: Determine when a series of in-order frames is present. WDI always expects 802.11 headers.įor each RX MPDU, determine which slot of the Rx reordering array it goes to. Replace non-initial A-MSDU subframe headers with 802.11 headers, using the 802.11 header fields from the initial A-MSDU subframe as appropriate.ĭuring A-MSDU deaggregation, the non-initial MSDUs of the A-MSDU need their 802.3 header replaced by a generic 802.11 header. The operating system performs countermeasures if needed. Decapsulate the security header and footer. The target's decryption is bypassed.ĭecompose an RX A-MPDU into individual MPDUs.ĭecompose an RX A-MSDU into individual MSDUs.Įach RX MSDU is placed into a separate buffer.įor security types that involve an MSDU-level MIC, verify the received MIC. In host-implemented FIPS mode, the decryption is done within the host software. Functionĭecrypt the frame contents using the security type and security key specified for the sender. The following is a list of RX operations and offloads. Frame forwarding (forwarding decision and actuation).These main categories of operation offloads are configurable.
