[PATCH] ixgbe: remove magic constant in ixgbe_reset_hw_82599()

[PATCH] ixgbe: remove magic constant in ixgbe_reset_hw_82599()

[Jiri Kosina]

From: Jiri Kosina <jkosina@suse.cz>

ixgbe_reset_hw_82599() resets the value of hw->mac.num_rar_entries to 
pre-defined value of 128. Let's get rid of that hardcoded literal, and use 
IXGBE_82599_RAR_ENTRIES instead, the same way the normal initialization 
path does.
