You can find them on b43-dev ML archive. You can copy them and paste into 3 separated text files. However to make it easier to you, I've also uploaded them to http server: http://files.zajec.net/enable-ht/0001-b43-Relax-requirement-for-descriptors-to-be-in-the-D.patch http://files.zajec.net/enable-ht/0002-b43-use-8K-buffers-for-64-bit-DMA-to-workaround-hard.patch http://files.zajec.net/enable-ht/0003-b43-make-HT-PHY-support-experimental.patch Save all that 3 files on your disk and then do: cd /foo/bar/wireless-next git am 0001-b43-Relax-requirement-for-descriptors-to-be-in-the-D.patch git am 0002-b43-use-8K-buffers-for-64-bit-DMA-to-workaround-hard.patch git am 0003-b43-make-HT-PHY-support-experimental.patch After that use "make menuconfig", enable BCMA, enable support for BCMA in b43 and enable HT support in b43. -- Rafał _______________________________________________ b43-dev mailing list b43-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/b43-dev
