There are two types of WLAN IPA exceptions, where WLAN driver is
involved for packet processing.
One is for RX exceptions, such as ICMP or Intra-BSS packets.
The other one is for WDI 1.0 MCC TX SW path, where packet queueing
is happening in WLAN driver.
In both cases, skb is allocated in IPA driver. If NBUF_MEMORY_DEBUG
is defined and qdf_net_buf_debug_acquire_skb() is not invoked for
the skb, qdf_nbuf_free() will trigger ASSERT to report unallocated
buffer.
For early processing of RX exceptions, dev_kfree_skb_any() needs to
be called instead of qdf_nbuf_free() otherwise above ASSERT will be
triggered.
For MCC TX SW path, ipa_free_skb() should be called to free skb to
IPA driver.
