Server is a machine which provides (shares) a \ 16USB device. Client is a machine which uses USB device provided by server \ 17over the network. The USB device may be either physical device connected \ 18to a server or software entity created on a server using USB gadget subsystem." 19 20LICENSE = "GPLv2" 21LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/GPL-2.0-only;md5=801f80980d171dd6425610833a22dbe6" 22DEPENDS = "virtual/kernel udev" 23PROVIDES = "virtual/usbip-tools" 24 25inherit kernelsrc autotools-brokensep 26 27do_configure[depends] += "virtual/kernel:do_shared_workdir" 28 29# We need to set S, for not being set to STAGING_KERNEL_DIR, and by that 30# be wiped when we prune dest below.
