  Changed paths:
    M sys/dev/ena/ena.c
    M sys/dev/ena/ena.h

  Log Message:
  -----------
  Due to the uninitialized stack variable, the ena(4) driver will exceed the
maximum tx burst size, leading to device resets, making the device unusable.

Additionally, the calculation of the tx burst size includes division by the
uninitialized stack variable. If the stack variable is 0, this will cause
division by 0 in the kernel, leading to a kernel panic.
