After fixing the remaining ifup bug (as expected, it was easy), I have some initial numbers on the new kernel driver versus the stock vendor driver on the G1:
| driver | avg ping ms | netperf mbit/s |
| tiwlan | 65.231 | 7.53 |
| wl1251 | 8.565 | 3.82 |
So, better on latency, worse on throughput. wl1251 is also quite a lot larger when taking all of cfg80211/mac80211 into account, though I didn’t spend any time trying to tweak the size in the build. Well, at least the code doesn’t make you want to poke your own eyes out.
