VLAN support + madwifi-r3314 + kernel > 2.6.30


after porting i was testing the features of the AP. while testing VLAN was not working with
the kernel while looking at the "netdevice.h" file the net_device structure coding has been changed from the kernel version 2.6.29 onwards.
But madwifi supports only kernels upto 2.6.28

Now its time to add the patches into madwifi code to add support for vlan....

Got the link from the below site

added the patches manually ... finally it started working...... tested upto 8 VAPS with 8 different VLAN tags....

Linux Embedded Board Partition confusions


After board bring up (LS-SR71), now need to add the option firmware upgrade through WEB-GUI...
For that i need to use mtd utilities (MTD)
Inside board,
When i give "cat /proc/mtd" i can see 5 partitions
mtd0: "redboot"
mtd1: "kernel"
mtd2: "rootfs"
mtd3: "FIS directory"
mtd4: "RedBoot config"

but when in /dev/ directory there are 7 mtd devices(both character device and block device)
namely mtd0 to mtd6 and mtdblock0 to mtdblock6 ....

I can't write my kernel file in mtd1.
only possible way is writing kernel in mtd2 and rootfs in mtd4 ....

I want some explanation... ??
