1. A method for Internet Protocol (IP) packet handling performed by a first processor of a wireless device, comprising:
receiving an IP packet of a downlink (DL) data stream after layer 2 (L2) processing on the wireless device, wherein the DL data stream is provided to the wireless device via a connection to a radio access network (RAN) and the IP packet is at least in part decoded from a wireless transmission of the RAN via the L2 processing on the wireless device;
determining whether the IP packet is a prioritized packet after the L2 processing on the wireless device;
sending the IP packet to a second processor of the wireless device using a prioritized traffic handling configuration in response to determining that the IP packet is a prioritized packet, wherein the prioritized traffic handling configuration is configured to have a lower latency than a default traffic handling configuration used for sending non-prioritized IP packets from the first processor to a third processor of the wireless device and wherein the default traffic handling configuration applies a packet aggregation to non-prioritized IP packets after L2 processing and the prioritized traffic handling configuration sends the IP packet to the second processor without any aggregation;
receiving a second IP packet of an uplink (UL) data stream from the second processor of the wireless device;
determining whether the second IP packet is a prioritized packet; and
sending the second IP packet to the RAN using an UL prioritized traffic handling configuration in response to determining that the second IP packet is a prioritized packet, wherein the UL prioritized traffic handling configuration is configured to have a lower latency than a default UL traffic handling configuration used for sending non-prioritized IP packets.
