Subject: [PATCH 3.11 052/137] be2net: set EQ DB clear-intr bit in be_open()

3.11.10.15 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Suresh Reddy <Suresh.Reddy@...lex.com>

commit 4cad9f3b61c7268fa89ab8096e23202300399b5d upstream.

On BE3, if the clear-interrupt bit of the EQ doorbell is not set the first
time it is armed, ocassionally we have observed that the EQ doesn't raise
anymore interrupts even if it is in armed state.
This patch fixes this by setting the clear-interrupt bit when EQs are
armed for the first time in be_open().
