Mithlesh Thukral 3e2facef86 NetXen: Fix ping issue after reboot on Blades with 3.4.19 firmware 
NetXen: Fix initialization and subsequent ping issue on 3.4.19 firmware
This patch fixes the ping problem seen X/PBlades after the adapter's
firmware was moved to 3.4.19. After configured interface up, ping
failed.
NetXen adapter couldn't accept ARP broadcast packet. Manual addition of
MAC address in the ARP table, made ping work.
NetXen adapter should finish initilization after system boot. But looks
NetXen adapter didn't initilization correctly after system boot up.
So have to re-load the firmware again in probe routine.
Also re-initilization netxen_config_0 and netxen_config_1 registers.
