You can also do

make drivers/net/dsa/microchip/ksz_ethtool.o
make drivers/net/dsa/microchip/ksz_ethtool.S

etc to get any of the intermediary files from the build process.

Also

make drivers/net/dsa/microchip/

will build everything in that subdirectory and below. That can be much
faster, especially when you have an allmodconf configuration and it
needs to check 1000s of modules before getting around to building the
one module you just changed. FYI: the trailing / is important.
