Qualcomm IP Accelerator (IPA) modem offload engine
A networking offload engine built into Qualcomm Snapdragon mobile and modem SoCs that handles packet routing, filtering, and acceleration between the cellular modem and the application processor. It lets phones, tablets, and Snapdragon-based laptops move LTE and 5G traffic without burning CPU cycles, and it appears in chips from the sdx65 modem through recent sm8550-class SoCs.
recommendation
It should stay because this is the in-kernel driver for Qualcomm's IP Accelerator block, an active networking offload engine found in modern Snapdragon SoCs and modem parts like the sm8550 and sdx65. Upstream development is still going strong, with new platform support and configuration revisions being added as recently as 2026, and Qualcomm continues to ship new Snapdragon hardware that depends on it. There is no alternative driver because IPA is a Qualcomm-specific hardware block.

Upstream IPA development remained active in 2026, including new IPA v5.2 configuration support.

Upstream IPA development also added Eliza platform configuration in 2026, indicating enablement for newer Qualcomm hardware rather than retirement.

Qualcomm was still launching Snapdragon X-series products and OEM designs in 2025, supporting the conclusion that Qualcomm SoC families using this class of networking/modem plumbing remained in new products.
codex reasoning notes (technical)
`mcp__lore_http__.lore_file_timeline` on `drivers/net/ipa/ipa_main.c` showed sustained traffic through 2026, including fixes and new platform support, so this is an actively maintained driver. A `lore_regex` search for remove/deprecate terms did not surface IPA-specific removal discussion; a `lore_path_mentions` attempt timed out, so absence of removal talk is moderate-confidence rather than absolute. `exec_command` on local tree confirmed the driver is the Qualcomm IP Accelerator used in many Qualcomm SoCs. Web search found LKDDb coverage and a Qualcomm 2025 Snapdragon X product announcement; combined with 2026 upstream enablement, that supports `hardware_still_sold_new_in_2025 = true`. No natural replacement driver exists because IPA is a hardware-specific Qualcomm block, so recommendation is to keep.
