+ * the kernel BPF logic.
+ *
+ * Highlights:
+ * 1. CONFIG_HZ .kconfig map is used.
+ * 2. In bictcp_update(), calculation is changed to use usec
+ *    resolution (i.e. USEC_PER_JIFFY) instead of using jiffies.
+ *    Thus, usecs_to_jiffies() is not used in the bpf_cubic.c.
+ * 3. In bitctcp_update() [under tcp_friendliness], the original
+ *    "while (ca->ack_cnt > delta)" loop is changed to the equivalent
+ *    "ca->ack_cnt / delta" operation.
