Summary
octeontx2-af: CGX: fix bitmap leaks
Details

In the Linux kernel, the following vulnerability has been resolved:

octeontx2-af: CGX: fix bitmap leaks

The RX/TX flow-control bitmaps (rxfcpfvfbmap and txfcpfvfbmap) are allocated by cgxlmacinit() but never freed in cgxlmacexit(). Unbinding and rebinding the driver therefore triggers kmemleak:

unreferenced object (size 16):
    backtrace:
      rvu_alloc_bitmap
      cgx_probe

Free both bitmaps during teardown.
