Subject: [2/5][BNX2]: Add missing wait in bnx2_init_5709_context().
Date: Mon, 04 Jun 2007 17:00:35 -0700	[thread overview]
Message-ID: <1181001635.5275.13.camel@dell> (raw)

[BNX2]: Add missing wait in bnx2_init_5709_context().

For correctness, we need to wait for the MEM_INIT bit to be cleared
in the BNX2_CTX_COMMAND register before proceeding.
