The error is the following: bnx2: Chip not in correct endian mode bnx2: fw sync timeout, reset code = 404001d This error was caused because the way pci_restore_state() is working after commit 4b77b0a2ba27d64f58f16d8d4d48d8319dda36ff ("PCI: Clear saved_state after the state has been restored").

The document about rp_filter is out of date. Now, setting conf/all/rp_filte with 0 can also enable source validation. Update the document according to the commit.
