open an ieee80211 device

The function moep_dev_ieee80211_open() is used to open an ieee80211 device.

Parameters

devname	the device name; This can either be the physical device name e.g. 'phy0' or an interface name e.g. 'wlan1'.
freq	the channel frequency in MHz
chan_width	the channel width
freq1	the first center frequency in MHz; This value may be ignored depending on the channel width.
freq2	the second center frequency in MHz; This value may be ignored depending on the channel width.
mtu	the MTU of the device; This includes all headers.

Returns

This function returns a moep device.

Return values

NULL	on error, errno is set appropriately.

Errors

These are some standard errors generated and returned by this function. Additional errors may be generated and returned from the underlying system calls.
