Add this memory region which is used in IPA v5.0 and higher. Link: https://github.com/LineageOS/android_kernel_qcom_sm8450-modules/commit/fc71d0972a2453cc29f873d723a355a902c6d69c Co-developed-by: Nazar Kompanets <redacted> Signed-off-by: Nazar Kompanets <redacted> Signed-off-by: Esteban Urrutia <redacted> --- From IPA v5.0 onwards, two memory regions for drop stats exist: one for the AP (that is, the driver) and one for the modem (Q6). This patch declares this memory region and only allows its presence if the IPA version is >=5.0. --- drivers/net/ipa/ipa_mem.c | 1 + drivers/net/ipa/ipa_mem.h | 1 + 2 files changed, 2 insertions(+)
