brcmfmac: Add P2P Action Frame retry delay to fix GAS Comeback Response failure issue
It was observed that P2P Cert. 5.1.19: DEVUT responds to Service
Discovery request failed due to DUT did not send GAS Comeback Response
after receiving request from test bed P2P peer. To fix this issue,
we need to add P2P Action Frame retry delay to enhance P2P connection
under VSDB and noisy environment, since the peer can be in other
channels under VSDB.
