+
+This report focuses on the efforts using permissively licensed Linux wireless drivers, mostly unmodified, on FreeBSD, as well as preparing the native net80211 stack for support of newer standards.
+
+==== Mediatek mt76 support
+
+A call for testing was put out for mt7921 based PCIe chipsets (MT7920E; MT7921E, also known as AMD RZ608; MT7922E ,also known as AMD RZ616).
+This is based on ongoing reviews, mostly to replace an old shortcut in LinuxKPI for struct page.
+Despite great interest in the driver the previous years we have not had a lot of feedback.
+
+Work to support further mt76 chipsets will continue.
+
+==== Realtek rtw8x support
+
+Thanks to the debugging of users the situation has slightly improved.
+It is expected that Linux v7.3 has a lot of bug fixes in the drivers but due to the timeline of Linux and FreeBSD release schedules may only hit main once again.
+Further issues have to worked on and fixed still.
+
+==== LinuxKPI USB support
+
+In previous reports we have reported that this was blocked on a compiler option.
+During Q3 we found a way which can limit the scope to just LinuxKPI USB drivers.
+There is ongoing work to simplify the build framework for this.
+While there are rough edges still, especially around teardown and unplug we hope to put out a stack of changes for review or a tree for testing during October.
+
+==== Native net80211 updates (tech debt)
+
+Initial work to remove workarounds from LinuxKPI and fix net80211 are ongoing.
+
+==== Espressif Systems ESP32-E22 support
+
+The current upstream driver from Espressif Systems on Github v0.6 has been ported to FreeBSD.
+Initial changes to fix compiler warnings were submitted back as pull requests.
+The driver is currently awaiting a vendor import and to be followed by an unifdef within the FreeBSD tree as upstream supports a wide range of Linux versions.
+Special thanks go to Espressif Systems for providing me with two E22 sample cards in order to test the port.
