ixgbe: Correct BASE-BX10 compliance code
[ Upstream commit f72ce14b231f7bf06088e4e50f1875f1e35f79d7 ]
SFF-8472 (section 5.4 Transceiver Compliance Codes) defines bit 6 as
BASE-BX10. Bit 6 means a value of 0x40 (decimal 64).
The current value in the source code is 0x64, which appears to be a
mix-up of hex and decimal values. A value of 0x64 (binary 01100100)
incorrectly sets bit 2 (1000BASE-CX) and bit 5 (100BASE-FX) as well.
Fixes: 1b43e0d20f2d ("ixgbe: Add 1000BASE-BX support")
