Subjectkernel regression ref networking

I reported since 2.6.27 that there has any kernel regression, because networking isn't working with ethernet cards, on all my computers, I supposed the problem has to do with some new features or parameters of the kernel config.

Meanwhile I found more narrow what can be the reason. For example, last night I compiled 2.6.29-rc7-git4 one time with an 'old' configuration sucessful since 2.6.29-rc6-git5, where internet / eth-cards still are working, and with a slightly changed new config, where it's not more working.

Below the differences between the two configs. One of these different parameters / new features causes that internet / eth dont work more at all, beginning with that ping 192.168.1.1 (modem directly connected with the computer via eth0) dont get response.

With this, someone of the specialists perhaps can quickly see what of the new parameters / options causes the total inoperability of networking, and throw this new feature out from the kernel, because its completely useless.

It should be something included at the time of 2.6.27 because at that time the problem begun.
