118 * Interface flags are of two types: network stack owned flags, and driver
119 * owned flags. Historically, these values were stored in the same ifnet
120 * flags field, but with the advent of fine-grained locking, they have been
121 * broken out such that the network stack is responsible for synchronizing
122 * the stack-owned fields, and the device driver the device-owned fields.
123 * Both halves can perform lockless reads of the other half's field, subject
124 * to accepting the involved races.
126 * Both sets of flags come from the same number space, and should not be
127 * permitted to conflict, as they are exposed to user space via a single

134 * (n) if_flags field written only by the network stack, read by either the
136 * (d) if_drv_flags field written only by the device driver, read by either
137 * the stack or driver.
