At the moment ipfs(8) is a tool that can be easily abused. Though the
concept is sound the implementation needs some work.

ipfs(8) should be considered experimental at the moment.

This commit also makes ipfs support in the kernel optional.

Add opt_inet.h and opt_usb.h to make linux module buildable standalone.

(cherry picked from commit c5f906d32d2bc8e37f1e1911382e27af7e6240ff)

This driver is heavily obfuscated, and causes a -Werror warning with
clang 18 now:

  sys/dev/ce/tau32-ddk.c:358:10: error: 'const' attribute on function returning 'void'; attribute ignored [-Werror,-Wignored-attributes]
    358 | ((const))nvqbt(void){__asm __volatile("repe; nop; repe; nop;"
        |          ^

Supress the warning since the driver can never be fixed. Direct commit
to stable/13, since the driver has been removed in 14.x and later.
