This is the fix for the following problem: https://bugzilla.redhat.com/show_bug.cgi?id=227657 The bnx2 device 5706 complains about MSI not working behind a ServerWorks HT1000 PCIX bridge. An earlier commit to fix the problem: e3008dedff4bdc96a5f67224cd3d8d12237082a0: "PCI: disable MSI by default on systems with Serverworks HT1000 chips" was not entirely correct, and has been reverted. MSI does not work on the PCIX bus because the BIOS did not set the HT_MSI_FLAGS_ENABLE bit in the HyperTransport MSI capability on the bridge. We use the existing quirk_msi_ht_cap() to detect the problem and disable MSI in all buses behind it. Signed-off-by: Michael Chan Cc: Anantha Subramanyam Cc: Naren Sankar Signed-off-by: David S.

A reasonably common problem with some devices is that they will disable MSI generation when the INTX_DISABLE bit is set in the PCI_COMMAND register. Quirk this explicitly, guarding the pci_intx() calls in msi.c with this quirk indication. The first entries for this quirk are for 5714 and 5780 Tigon3 chips, and thus we can remove the workaround code from the tg3.c driver. Signed-off-by: David S.
