8139too: [cosmetic] fix incorrect register for flash-rom
I would like to submit a correction to the driver
drivers/net/8139too.c,
which in no way changes the compiled driver, but does change
the value of a previously incorrect value for the configuration
register address of Flash PROM on the network processor rtl8139C.
This corrected value is in accordance with the datasheet
for rtl8139C, and in addition this new value is indeed used
in other functional drivers that use this adapter for
programming a Flash memory chip in situ. But as said,
the two new constants are never referenced in the driver

ipsec: Fix xfrm_state_walk race
As discovered by Timo Teräs, the currently xfrm_state_walk scheme
is racy because if a second dump finishes before the first, we
may free xfrm states that the first dump would walk over later.
This patch fixes this by storing the dumps in a list in order
to calculate the correct completion counter which cures this
problem.
I've expanded netlink_cb in order to accomodate the extra state
related to this. It shouldn't be a big deal since netlink_cb
is kmalloced for each dump and we're just increasing it by 4 or
8 bytes.

tcp: advertise MSS requested by user
I'm trying to use the TCP_MAXSEG option to setsockopt() to set the MSS
for both sides of a bidirectional connection.
man tcp says: "If this option is set before connection establishment, it
also changes the MSS value announced to the other end in the initial
packet."
However, the kernel only uses the MTU/route cache to set the advertised
MSS. That means if I set the MSS to, say, 500 before calling connect(),
I will send at most 500-byte packets, but I will still receive 1500-byte
packets in reply.
This is a bug, either in the kernel or the documentation.
This patch (applies to latest net-2.6) reduces the advertised value to
that requested by the user as long as setsockopt() is called before
connect() or accept(). This seems like the behavior that one would
expect as well as that which is documented.
I've tried to make sure that things that depend on the advertised MSS
are set correctly.
