commit f9d6f94132f01d2a552dcbab54fa56496638186d upstream.
Without crc32, this driver fails to link:
arm-linux-gnueabi-ld: drivers/net/phy/dp83640.o: in function `match':
dp83640.c:(.text+0x476c): undefined reference to `crc32_le'
Fixes: 539e44d268 ("dp83640: Include hash in timestamp/packet matching")

The IEEE 1588 standard defines a method to precisely
|
|
synchronize distributed clocks over Ethernet networks. The
|
|
standard defines a Precision Time Protocol (PTP), which can
|
|
be used to achieve synchronization within a few dozen
|
|
microseconds. In addition, with the help of special hardware
|
|
time stamping units, it can be possible to achieve
|
|
synchronization to within a few hundred nanoseconds.

devices. If you want to use a PTP clock, then you should

also enable at least one clock driver as well.
