It was always like that for all Intel PMDs we have:

$ find lib/ -name '*_osdep.*' | grep -v acl
lib/librte_pmd_vmxnet3/vmxnet3/vmxnet3_osdep.h
lib/librte_pmd_ixgbe/ixgbe/ixgbe_osdep.h
lib/librte_eal/linuxapp/kni/ethtool/ixgbe/ixgbe_osdep.h
lib/librte_eal/linuxapp/kni/ethtool/igb/e1000_osdep.h
lib/librte_pmd_i40e/i40e/i40e_osdep.h
lib/librte_pmd_e1000/e1000/e1000_osdep.c
lib/librte_pmd_e1000/e1000/e1000_osdep.h

As I understand ND has it's own version of <drvname>_osdep.* for each OS they support.
We obviously modify it to fit DPDK purposes.
