Subject: [PATCH 3/6] e1000: convert regtest macro's to functions
Minimal macro to function conversion in e1000_ethtool.c
Adds functions reg_pattern_test and reg_set_and_check
Changes REG_PATTERN_TEST and REG_SET_AND_CHECK macros
to call these functions.
Saves ~2.5KB
Compiled x86, untested (no hardware)
