hostapd is pretty useless without regdb

Hi,

I’m trying to setup a hostap with Alpine. The problem is that Alpine is not shipping wireless-regdb which is needed to set the right freqs for your country. This restricts hostapd to a very limited set of allowed frequencies.

<code class="shell">
router:~# iw reg set DE
router:~# iw reg get
country 00: DFS-UNSET
        (2402 - 2472 @ 40), (6, 20)
        (2457 - 2482 @ 40), (6, 20), PASSIVE-SCAN
        (2474 - 2494 @ 20), (6, 20), NO-OFDM, PASSIVE-SCAN
        (5170 - 5250 @ 160), (6, 20), PASSIVE-SCAN
        (5250 - 5330 @ 160), (6, 20), DFS, PASSIVE-SCAN
        (5490 - 5730 @ 160), (6, 20), DFS, PASSIVE-SCAN
</code>

How to solve:

Create packages for crda and wireless-regdb (I think), see https://wireless.wiki.kernel.org/en/developers/Regulatory

Or copy db.txt from wireless-regdb into the kernel source directory and recompile the kernel with CONFIG_CFG80211_INTERNAL_REGDB, see https://wireless.wiki.kernel.org/en/developers/regulatory/crda

If you do not want to install CRDA on a host, you can simply enable the CONFIG_CFG80211_INTERNAL_REGDB on your kernel. Once enabled you can place the db.txt from the wireless-regdb into net/wireless/db.txt. The downside to using this option is that you will need to rebuild your kernel for any regulatory updates, therefore using CONFIG_CFG80211_INTERNAL_REGDB is not recommended.
