So I made some progress on this, three things:
1) I remember why I choose a to use a bit in my design, it's so that
it does not increase the costs of the checks in the fast paths.
test_bit(X) && test_bit(Y) can be combined into a single test by
the compiler.
2) We can't use the reference counting scheme, because we don't want
to let a second cpu into these protected code paths just because
another is in the middle of using a freeze too.
3) So we can simply put a top-level TX spinlock around these things.
Therefore all the hot paths:
a) grab _xmit_lock
b) check XOFF and FROZEN
c) only call ->hard_start_xmit() if both bits are clear
netif_tx_lock() does:
1) grab netdev->tx_global_lock
2) for_each_tx_queue() {
lock(txq);
set_bit(FROZEN);
unlock(txq);
}
and unlock does:
1) for_each_tx_queue() {
clear_bit(FROZEN);
if (!test_bit(XOFF))
__netif_schedule();
}
2) release netdev->tx_global_lock
And this seems to satisfy all the constraints which are:
1) Must act like a lock and protect execution of the code path
which occurs inside of "netif_tx_{lock,unlock}()"
2) Must ensure no cpus are executing inside of ->hard_start_xmit()
after netif_tx_lock() returns.
3) Must not try to grab all the TX queue locks at once.
This top-level tx_global_lock also simplifies the freezing, as
it makes sure only one cpu is initiating or finishing a freeze
at any given time.
I've also adjusted code that really and truly only wanted to
lock one queue at a time, which in particular was IFB and the
teql scheduler.
It's late here, but I'll start testing the following patch on my
multiqueue capable cards after some sleep.
