ixgbe: fix poll loop for FDIRCTRL.INIT_DONE bit
The loop in ixgbe_reinit_fdir_tables_82599() only polls for up to 100us resulting in failures to update the FDIR filter table at 1Gbps and 10Gbps when under load. The poll times for FDIRCTRL.INIT_DONE are 55us, 550us and 5.5ms for 10Gbps, 1Gbps and 100Mbps respectively. This patch sets the wait time to be the same as in ixgbe_fdir_enable_82599() Reported-by: Bhushan <shashi-sm@users.sf.net> Signed-off-by: Emil Tantilov <emil.s.tantilov@intel.com> Tested-by: Phil Schmitt <phillip.j.schmitt@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
