I do support this request. Since upgrading to Android 5, my N5 suffered from terrible WiFi lags which seem to be related to problems in IPv6 stack.
Disabling IPv6 resolves the problems (temporary solution) but this is not possible without rooting the device at this point.

I don't think it's a good idea to provide this ability, because non networking-savvy users may have no idea that the problems are related to IPv6 and thus won't know to disable it. Instead it's better to focus on ensuring that Android does not provide a bad experience on these networks.
Dustin, have you diagnosed the problem since your post on bug 36949180 ?

Description
public class Test extends FuzzerUtils {
public static final int N = 100;
public static long instanceCount=1L;
public static void main(String[] strArr) {
double d, dArr[]=new double[N];
int i, i1, i2;
init(dArr, -71.71433);
d = 1;
while (++d < 89) {
i1 = 1;
while (++i1 < 14) {
i2 = 1;
do {
Test.instanceCount -= (long)dArr[(int)(d + 1)];
} while ((i2 += 2) < i1);
}
}
System.out.println("Test.instanceCount = " + Test.instanceCount);
}
}
It prints:
Test.instanceCount = 249281
instead of:
Test.instanceCount = 261745
If I disable BCE as shown below:

then the problem is gone
To reproduce:
1. download latest AOSP
2. build aosp_arm
3. launch emulator
4. upload attached file classes.dex
5. run command adb shell "cd /data; dalvikvm -cp classes.dex Test"
